    Introducing Jawbone Sockets
    Hi! Sorry I'm so wildly inconsistent about blogging. I've just been hard at work on a lot of things. :) I ranted previously about the awful state of .NET socket libraries for game devs. I originally developed my new socket library inside the confines of my Jawbone lib, but the project evolved enough and sparked enough interest from third parties that I decided it was worth spinning off into its own focused project. Introducing... Jawbone.Sockets! Be sure to take a tour to become familiar with the API design. The sockets perform zero allocation (beyond the socket creation itself), and they indeed perform better than System.Net sockets, but the more time I spend with this library, the more I just enjoy the drastically simplified design. Span is the heart and soul of everything in this lib…  ( 5 min )

    Harmony in School Halls
    Harmony in School Halls School life is a symphony of sounds**, a rhythmic beat of lockers slamming, chatter of friends, and the steady hum of lessons. It's a world where we grow, learn, and develop social skills, and create memories that last a lifetime. From the chaotic morning rush to the evening reflection, school life is a journey of self-discovery, where we form meaningful relationships, discover our strengths and weaknesses, and learn to navigate the ups and downs of this journey. The school day begins with a chaotic symphony of alarm clocks, breakfast on-the-go, and a mad dash to catch the bus. As we burst through the school gates, the sounds of chatter and laughter fill the air, a cacophony of excitement and anticipation. School is where we form some of our most meaningful relationships, bond over shared interests, laughter, and adventures, and create memories that we'll cherish forever. Our friends are our support system, confidants, and partners in crime, and together, we navigate the ups and downs of school life, sharing our joys and sorrows. School is also about learning, growing, and developing new skills, where our teachers guide us, inspire us, and challenge us to reach our full potential. As the school day comes to a close, we reflect on what we've learned, what we've accomplished, and what we could do better tomorrow. We think about our goals, our aspirations, and our dreams. School life is a journey of self-discovery, where we learn to navigate the ups and downs, and develop the resilience and determination to overcome obstacles.

    Focus on one thing
    Time is a resource If there's one thing I don't have enough of, it's time. And by that I mean time for all my projects, for everything that interests me, for everything I would like to learn. I love learning new things. Definitely a great skill and practically indispensable in my job as a software developer. But sometimes it's also a curse. I always try to organize my time as well as I can. Sometimes it works more or less well. I believe that this one thing is the reason why projects are not fulfilling, don't work or simply fall by the wayside. Our brain can do many things, but one thing it cannot do. Multitasking. It is said that women are better at it than men. And that may be true. But it's still bad. It is both a curse and a blessing. But this skill of doing one thing with everything you have is incredibly powerful. It may sound like a fortune cookie saying, but you really can do anything with it. It's a superpower. One trap I often fall into is the fact that I believe that if I only do one thing, I have to do it perfectly. It has to be worth it, right? Bullshit. I wrote this blog mainly for myself. Of course I hope to help others but I personally struggle with this issue every day. Focus on one thing. Don't split your attention and energy. Bundle them. Quality over quantity!  ( 4 min )
    AI-Powered Hiring: From Inbox Chaos to Structured Data with Postmark & LLM
    This is a submission for the Postmark Challenge: Inbox Innovators. I built a web application that automates the initial stages of the hiring process by leveraging Next.js and Postmark's inbound email parsing feature. The application receives job application emails, uses an LLM (OpenAI GPT) to intelligently extract relevant information from the email body and any attached resumes (PDF or DOCX), and then stores this structured data in Firebase Firestore. This data, including candidate details, job application specifics, and the original parsed email, is then accessible via a dashboard for easy viewing and management.

    Containerized Java Microservices: A Modern Architecture Approach
    In the world of software development, designing a scalable and maintainable architecture is crucial for building a successful application. One approach to achieve this is by using containerization with Docker. In this article, we'll explore the benefits of using containerized Java microservices and provide a step-by-step guide on how to implement this architecture. Identify the microservices: Break down your application into smaller, independent services that can be developed, tested, and deployed separately. Choose a containerization platform: Select a suitable containerization platform, such as Docker, and install it on your development environment. Create a Dockerfile: Write a Dockerfile that defines the instructions for building and running your microservice. Build and run the container: Use the Dockerfile to build a Docker image and run the container. Integrate with other services: Integrate the containerized microservice with other services in your application. By following these steps, you can design a scalable and maintainable Java microservice architecture using containerization with Docker.

    Key Management Service in Kubernetes — Part 2
    Welcome back to our series on Key Management Service (KMS) in Kubernetes! In Part 1, we laid the groundwork; now, in Part 2, we're diving into the critical concept of encryption at rest. Simply put, encryption at rest in Kubernetes refers to how the API server encrypts data before storing it in etcd. Think of etcd as the brain of your Kubernetes cluster - it's where all your cluster's configuration data, state, and secrets live. By default, the Kubernetes API server stores resources in etcd as plain text. This means if someone gains unauthorized access to your etcd, they can read all your sensitive data, including secrets, without any effort. This is a significant security risk. While encryption at rest applies to any Kubernetes resource, in this series, we'll continue to focus on Secrets …  ( 7 min )

    Terminally in Love: Two Decades of Linux, One Shell at a Time
    👋 The Beginning It all started in 2005 — RHEL 3.0 and Oracle 8.x were the giants of the day.I wasn’t just installing software — I was absorbing a way of life. I still remember setting up BIND (probably Redhat 9 (not EL)) and attending a demo at Indian Air Force HQ, Subroto Park, New Delhi. My uniform had changed. But my mindset remained tactical — observe, adapt, deploy. Back then, there was no Stack Overflow, no YouTube how-tos. Just man pages, printed guides, and logs. And somehow, that made the learning stick deeper. 🧠 What Made Linux Stick? Simple. The terminal felt like home. I wasn’t chasing certs (though I earned my RHCE 4 in Dec 2005). I was chasing clarity — why a service failed, why a bootloader broke, how to recover from a corrupted /etc/fstab at 2 AM without breaking a sweat.…  ( 4 min )
    Unleashing AI to Hunt Down Database Code Leaks in Go
    Hi there! I'm Shrijith Venkatrama, founder of Hexmos. Right now, I’m building LiveAPI, a first of its kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand and use APIs in large tech infrastructures with ease. Database connection leaks in Go can silently kill your app’s performance. Open connections pile up, resources get hogged, and suddenly your app is choking under the weight of its own database calls. I built db_leaks.py, a Python script that uses AI to scan Go codebases for PostgreSQL connection issues. It’s not perfect, but it’s a solid tool to catch problems like unclosed connections, idle connection overuse, or redundant sql.Open() calls.

    Creating a Google Homepage Clone with HTML and CSS
    Today, I took my front-end web development skills one step further by building a clone of the Google homepage using just HTML and CSS. It was a fun and educational exercise that helped me understand how minimalistic yet powerful design can be. Google's homepage is simple, clean, and iconic — making it the perfect project for practicing HTML and CSS layout skills. Even though it looks basic, replicating its layout and responsiveness was a great challenge. HTML5 for structure CSS3 for styling A code editor like VS Code Google Chrome for testing and inspecting elements I started by dividing the page into key sections: Header – Contains the navigation links like Gmail and Images, and the grid icon (Google Apps). Main Section – Contains the Google logo, search bar, and the buttons ("Google Search" and "I'm Feeling Lucky"). Footer – Contains regional and policy links. Here’s a snippet of the basic HTML structure: Google Clone I used Flexbox for layout alignment, making it easier to center the content both vertically and horizontally. I also replicated the rounded corners of the search bar, the subtle shadows, and hover effects on the buttons. Some CSS features I used: display: flex; justify-content: center; box-shadow border-radius :hover pseudo-classes Here’s what my version looks like: (You can insert a screenshot of your Google clone here) The importance of spacing and alignment in web design. How even a simple page can teach attention to detail. Improved my skills in using Flexbox and basic responsive design. Now that I’ve done a static clone, I’m thinking about adding: Responsive design for mobile screens. A dark mode toggle using JavaScript. A little animation to the buttons.  ( 3 min )
    Getters and Setters in JavaScript
    In JavaScript, getters and setters are special methods that allow you to control access to the properties of an object. They are primarily used to define object properties dynamically, encapsulate logic, and ensure data integrity. By using getters and setters, developers can control how properties are read and written without directly exposing the underlying data structure. Getter: A method that gets the value of a specific property. Setter: A method that sets or updates the value of a specific property. They are defined using the get and set keywords inside an object or class. Encapsulation: Hide the internal representation of data. Validation: Apply logic before assigning or retrieving values. Computed Properties: Dynamically calculate values based on other properties. Consistency: Unifo…  ( 4 min )
    AI Discovers Over One Million New Species, Transforming Drug Discovery
    A UK-based biotech company, Basecamp Research, is using artificial intelligence and environmental DNA to uncover a vast new world of biology. By sampling DNA from some of the planet’s most remote and untouched ecosystems, the company has identified over one million previously unknown species. These discoveries are not just academic. They are fueling a next-generation AI platform designed to radically accelerate drug discovery. The company’s genomic database is already among the largest of its kind. It is being used to train AI models that predict protein structures, functions, and interactions at unprecedented accuracy. This includes boosting tools like AlphaFold, which helps researchers visualize the shape of proteins based on genetic code alone. A major focus of the project is the identification of new large serine recombinases, a type of enzyme that can precisely insert large DNA sequences into the genome. These enzymes are considered highly promising for future gene therapies, including for cancer and rare genetic disorders. Basecamp Research is also trying to set a new standard in ethical science. The team works directly with local researchers and governments in the regions where DNA samples are collected. In return, partner countries receive royalties and scientific credit, avoiding the extractive models of earlier biotech ventures. This combination of field biology, advanced sequencing, and deep learning could reshape how we find drugs, understand evolution, and build genetic tools. It is a powerful example of how AI, when paired with real-world data, can help uncover the deepest layers of life on Earth.

This article examines their historical contexts, operational advantages, implementation challenges, and optimal use cases, providing actionable insights for organizations navigating modern data management. Developed in the 1990s, ETL emerged as a response to technological constraints, including expensive storage and limited computational resources. Its sequential process—extracting data from heterogeneous sources, transforming it into standardized formats, and loading it into centralized repositories—prioritized storage efficiency by discarding raw data post-transformation.

Elliot was brave, skilled, and a master of JavaScript sorcery, but he had one fatal flaw: He feared writing docs. In his kingdom, documentation was handled through monstrous WYSIWYG editors. They promised magic — bold with a click! headings with a shortcut! — but Elliot knew the truth. They: Lagged like his old PC running Electron apps. Spat out bloated HTML like a sneeze of tags. Turned simple thoughts into formatting chaos. He felt trapped. He had thoughts to share with the dev.to village. Wisdom to pass on. But the…  ( 4 min )

    Math.random(): Math.random() is a built-in function that returns a floating-point number between 0 (inclusive) and 1 (exclusive). This means the result is always >= 0 and < 1. Basic usage const randomNumber = Math.random(); console.log(randomNumber); // e.g., 0.34784310291847 Get a random number between 0 and a specific number: const randomUpTo10 = Math.random() * 10; // 0 <= result < 10 Math.floor() is a method that rounds a number down to the nearest integer. Examples: Math.floor(4.9); // 4 Math.floor(4.1); // 4 Math.floor(4.0); // 4 Math.floor(-4.1); // -5 Math.floor(-4.9); // -5 Array is a data structure used to store multiple values in a single variable. Creating an Array const fruits = ["apple", "banana", "cherry"]; const numbers = [1, 2, 3, 4, 5]; The length property sets or returns the number of elements in an array.

    If you are just starting to look into AI (or any software) development, you might hear terms like API, SDK, etc. One of my friends who just got into this hype of AI development asked me these questions, and he did not have any technical background: “What are APIs? What are the differences between API and SDK?” I thought it would also be nice to have a simple-to-understand explanation for you guys. Let’s start with the API. To put it simply, API is how software talks to each other. If this is too vague, consider it a clearly defined way one program can request services or information from another. Instead of a human clicking a button, one piece of software makes a structured call to another. Many larger software platforms are providing API services to interact with their software. Let’s tak…  ( 7 min )

    📦WebSocket Broadcasting with hyperlane
    WebSocket Broadcasting with hyperlane The hyperlane framework natively supports the WebSocket protocol. Developers can handle WebSocket requests through a unified interface without dealing with protocol upgrades manually. This article demonstrates how to implement both point-to-point and broadcast messaging on the server side using hyperlane, along with a simple WebSocket client example. The hyperlane framework supports the WebSocket protocol with automatic server-side protocol upgrading. It also offers features such as request middleware, routing, and response middleware. Note: WebSocket responses must be sent using the send_response_body method. Using send_response will cause client-side parsing to fail, as it does not format the response according to the WebSocket protocol. In this ex…  ( 4 min )

    React vs Next Frontend: Which is better?
    React is a JavaScript library for User Interfaces, while Next is a full-stack framework build on top of React, You can think of it like a enhanced version of React with features like routing, server-side rendering, and better SEO capabilities. Reactjs Core Nextjs Core In React, routing is manual you have to set it up with tools like react-router. In Next.js you just create a folder in the app directory and name it based on your route name (ex: about,dashboard), No boilerplate code needed. For SEO and performance, Next.js uses SSR and static generation. It can pre-render HTML on the server, which loads faster and is more SEO-friendly. Dynamic pages can also be server-rendered in chunks — Next figures out what to serve based on the user's request and only sends what's needed. If a page uses use client, the server sends that component's JavaScript to the browser, which then renders it client-side. By the way on what tech do you build frontend?  ( 3 min )
    Oracle APEX Tutorials Website
    You know that feeling when you're trying to learn a specific Oracle APEX pattern and every tutorial either assumes you're a complete beginner or jumps straight into enterprise-level complexity? The basics are too basic, the advanced stuff skips too many steps. That's why I created Oracle APEX Tutorials. Real-world scenarios, practical examples, and the stuff that actually matters when you're building applications people will use. Oracle's docs are comprehensive but not always practical. Community forums solve specific problems but don't show the bigger picture. I wanted something in between - structured tutorials that assume you know Oracle APEX basics but need guidance on doing things the right way. Each tutorial focuses on a specific problem I've actually encountered: building responsive dashboards, handling complex validations, optimizing performance with large datasets. No contrived examples, just solutions that work in production.  ( 3 min )
    How I Build a Diabetes Risk App with Python & ML
    DiaGuide: Diabetes Risk Prediction App 👋 Introduction Hi there! Last week, I built my first fully functional website, implementing AI to predict diabetes risk using historical data. This was my first time publishing a real, working website—and I am honestly proud of the result. And I built all this during 48-hour hackathon, working solo. I used Streamlit for the UI, scikit-learn for the AI training, and a model. Here is how: When the project topic was first released, I was slightly surprised to see healthcare 💓 — most of the hackathons I had joined previously allowed more open-ended, general tech solutions. But then I started thinking 🤔, and this pushed me to research more deeply. Since I was good at data analysis and developing ML models, I decided to focus on those are…  ( 5 min )
    Industrial vs Consumer TFT Displays: Why They’re Not Interchangeable
    TFT displays are ubiquitous—from smartphones and tablets to industrial HMIs and outdoor terminals. But under the surface, not all TFT panels are created equal. A display designed for a handheld device is fundamentally different from one engineered for 24/7 operation in a high-temperature, high-vibration environment. In this post, we’ll explore the core differences between industrial and consumer-grade TFT displays, and why choosing the wrong type can lead to premature failure, performance issues, or even safety risks in demanding applications. An industrial TFT (Thin-Film Transistor) display is built to operate in harsh, mission-critical environments—think factory automation, medical equipment, agricultural systems, and outdoor kiosks. These displays prioritize long-term reliability, therm…  ( 4 min )

    🌟 Beginner's Guide to Arrays and Length in Programming
    Sure! Here's a simple and beginner-friendly blog post about learning arrays and length in programming. This example is based on JavaScript, but I can adapt it to another language if you prefer. If you're just starting your programming journey, two important concepts you'll often hear are arrays and length. Let’s break them down in a simple way. An array is a way to store multiple values in a single variable. let fruits = ["apple", "banana", "cherry"]; Here, fruits is an array that holds 3 values: "apple" "banana" "cherry" You can think of an array like a box with compartments. Each compartment has a number (called an index), and it holds one item. Index Value 0 "apple" 1 "banana" 2 "cherry" 🧠 Remember: Indexes start at 0, not 1. Want to get "banana"? You use its index: console.log(fruits[1]); // Output: banana Every array has a property called length, which tells you how many items are inside. console.log(fruits.length); // Output: 3 Even if you don’t know what's in the array, .length helps you find out how many items it contains. You can add new items using .push() and remove with .pop(): fruits.push("mango"); // Adds "mango" to the end console.log(fruits); // ["apple", "banana", "cherry", "mango"] fruits.pop(); // Removes the last item ("mango") console.log(fruits); // ["apple", "banana", "cherry"] You can loop through arrays using a for loop: for (let i = 0; i < fruits.length; i++) { console.log(fruits[i]); } An array stores multiple values in one variable. You access values using index numbers, starting from 0. Use .length to find how many items are in the array. Arrays are super useful for organizing data and are used in almost every programming language! Let me know if you'd like this blog translated into Hindi, Tamil, or another language, or if you want examples in Python, Java, or C++.  ( 4 min )
    🧠 From Chaos to Clarity: How I Designed a Structured Logging System for My Application
    Logging is deceptively tricky. When I started building my app, I assumed logging would be simple — just add logger.info() or logger.error() where needed. But as the app grew, so did the problems: Inconsistent logs from different layers Inability to trace what failed and why Unstructured logs that Fluent Bit couldn’t reliably parse Missing context (like response time, request ID) in error logs I had questions. A lot of them. Here's how I answered them — and built a logging system that’s clean, structured, and future-ready. Doubt: “Logging needs all details at the end (status code, time taken, etc.), but most of those are only known at the response stage. Should I log in request and response both?” Answer: ✅ Logging once — at the response/finalization stage — makes more sense. You get …  ( 5 min )
    Top 5 Open Source Vector Search Engines: A Comprehensive Comparison Guide for 2025
    Introduction Vector search, also known as vector similarity search, has quickly evolved from an experimental technology to a must-have component in many AI applications. As developers and technical leaders, we're increasingly looking for ways to handle similarity-based queries that traditional databases simply weren't designed to handle efficiently. Whether you're building a product recommendation system or implementing semantic search, the underlying challenge is the same: how do you efficiently find the "nearest neighbors" to a query vector in a potentially massive dataset? That's where vector search engines come in. The good news is that the open source community has stepped up with multiple high-quality options. The challenging part?

    RSUs — What if you turned them into ETFs?
    Thinking of cashing out the RSUs and investing the money elsewhere? Let’s run the numbers first! In the previous blog post, we talked about the RSUs portion of an employee’s compensation. At first, they are granted to you, and when the time comes, they are vested: The shares are yours! Once you can vest your shares, you need to pay income tax on them. For example, if you get 10 shares worth $100 each at the time of vesting, you need to pay 52% of their value to taxes (that number depends on where you live). This means that for those 10 shares, you need to pay $520 in taxes. We compared three options to handle the stocks given to you by the company: Sell all when received: sell all 10 shares and take $480 home. Sell to cover taxes: sell 6 shares, invest 4 shares, and take $80 home. Keep …  ( 6 min )

    The Truth About Preloading in Modern Web
    One of the most common ways to optimize the size of an application's bundle is code splitting. With code splitting, we divide the application into smaller chunks that can be loaded on demand. This allows us to reduce the amount of JavaScript that needs to be downloaded and parsed when the user first opens the app. A simple and widely used approach to code splitting is splitting by page. The logic is straightforward: when a user opens Page A, there’s no need to load the code for Page B at that moment. This approach provides a significant improvement in initial load time, which is especially important for large applications. However, like any solution, this method comes with trade-offs. While first-time loading becomes faster, navigating between pages can feel slower. When the user switches …  ( 6 min )

    Don't Panic! Handle Errors Gracefully with "panic", "defer", and "recover" in Go
    In the world of Go development, unexpected situations can arise – bugs, invalid inputs, or resource exhaustion. When these critical errors occur, Go has a built-in mechanism called panic to signal that something unrecoverable has happened. However, simply letting your program crash isn't the most user-friendly or robust approach. This is where the powerful duo of defer and recover comes into play. They provide a way to intercept and handle panics gracefully, allowing your program to potentially clean up resources, log the error, and even continue execution (in specific scenarios). Let's dive into each of these concepts with clear, practical examples. panic A panic in Go is a runtime error that stops the normal execution flow of the current goroutine. It's typically triggered when the pro…  ( 7 min )

    React Native SDK Architecture (JSI-Based New Architecture)
    React Native’s new design is a big improvement over the old way it worked.
Instead of using a slow "bridge" to talk between JavaScript and native code, it now uses a faster system called JSI (JavaScript Interface). It also adds TurboModules and a new way to draw screens called the Fabric Renderer. Thanks to these updates, apps run faster, look more consistent, and can connect better with native features (like camera or GPS).
This document explains the different layers and how the parts of a modern React Native SDK work together using this new system. Old Architecture vs New Architecture Layered Architecture Overview This is where you write your app using JavaScript or TypeScript. All your business logic (how your app works) is written here.

    Crypto vulnerable if CFTC not given authority, says ex-chair Behnam
    Former Commodity Futures Trading Commission Chair Rostin Behnam has said the crypto market will remain unregulated unless the agency he led is given greater authority. In a May 28 Bloomberg TV interview, Behnam sided with the crypto industry on its long-standing argument that cryptocurrencies are commodities. “If you look at existing law, the few largest tokens are commodities, which means the SEC does not have jurisdiction over those tokens, which include Bitcoin and Ether,” he said.  He added that the Securities and Exchange Commission currently cannot properly regulate crypto because its law doesn’t allow it to regulate commodities, and the CFTC cannot regulate because it is a derivatives regulator. Without new authority for the CFTC to regulate “cash markets in digital assets, non-secu…

    Introduction: Imagine an AI that can generate photorealistic human faces of people who don’t exist, or paint original artwork in the style of Van Gogh. This isn’t science fiction—it’s the power of Generative Adversarial Networks (GANs), one of the most exciting breakthroughs in modern AI. In this post, we’ll break down how GANs work, why they’re revolutionary, and where they’re being used today. For Beginners: Generative AI = An artist 🎨 Creates new things (e.g., fake cat images, music, or text). Discriminative AI = A detective 🔍 Classifies existing things (e.g., "Is this image a cat or a dog?"). GANs are a type of generative model—they create rather than just classify. For Pros: Generative models learn the joint probability p(X,Y) (how data and labels co-occur). Discriminative models …  ( 5 min )

    Is AI Going to Take Our Jobs? A Software Engineer’s Experience with LLMs
    Over the past few years, there has been considerable discussion about how AI might replace all our jobs. For a long time, I completely ignored the topic; most of it sounded like pure bu11SH1T. I had already studied neural networks and understood the basics of LLMs, Machine Learning, Deep Learning, Natural Language Processing, and Expert Systems. I had even tested a few generative AI tools, but none of them impressed me; they were buggy, full of hallucinations, and constrained. Last year (2024), I revisited the subject with more focus.

    Experimenting with Ai MultiAgents
    After completing the Azure AI Foundry agentic AI challenge, the goal was to experiment with multi-agents. There was a lot to absorb around building and orchestrating agents using Azure and Semantic Kernel. So decided to experiment with simple model deployments using a chat completion model to gain deeper understanding especially with the azure ecosystem. I had a bunch of ideas floating around, but after a visit to nandos. I decided on something to improve their ordering system. Currently with their system customers scan a QR code on their table, get redirected to a website, place their order, and minutes later, their food arrives. It was smooth, efficient. How could Agents make this more flexible ? Hmmm? Something that uses speech? The upside of using voice as the main interaction is tha…  ( 6 min )

    Farbpsychologie im Webdesign: Die verborgene Macht hinter erfolgreichen Interfaces
    Hast du dich jemals gefragt, warum du auf manchen Websites sofort den "Kaufen"-Button findest, während du auf anderen orientierungslos umherirrst? Der Unterschied liegt oft nicht im Layout oder der Typografie, sondern in einer subtilen, aber mächtigen Komponente: der durchdachten Farbgestaltung. Farben sind weit mehr als dekorative Elemente - sie sind stille Verkäufer und emotionale Trigger, die innerhalb von Millisekunden wirken. Bevor ein Nutzer auch nur ein Wort auf deiner Website gelesen hat, hat sein Gehirn bereits die Farbwelt analysiert und erste Schlüsse gezogen. Die Zahlen sprechen für sich: Innerhalb von 50 Millisekunden entscheidet sich, ob ein Besucher deine Website als attraktiv empfindet Die richtige Farbwahl steigert die Markenerkennung um bis zu 80% Websites mit adaptiv…  ( 4 min )
    Claw Finding Algorithm Using Aegypti
    Claw Finding Algorithm Using Aegypti Frank Vega Information Physics Institute, 840 W 67th St, Hialeah, FL 33012, USA vega.frank@gmail.com In graph theory, a claw is a specific structure in an undirected graph, also known as a K1,3K_{1,3}K1,3​ graph. It consists of one central vertex (the "center") connected to three other vertices (the "leaves"), where the leaves are not connected to each other. Imagine a star with a hub city and three isolated towns connected only to the hub—that’s a claw! Formally, for a vertex set {u,v,w,x}\{u, v, w, x\}{u,v,w,x} , a claw exists if uuu (the center) is connected to v,w,xv, w, xv,w,x , but there are no edges among v,w,xv, w, xv,w,x .

    Taming the Server Beast: AWS EC2 vs. DigitalOcean vs. Linode for Node.js (No Ops Nightmares) 🐉⚡
    You’ve outgrown Heroku. Your Node.js app needs real muscle—more RAM, cheaper scaling, or gritty control. But the moment you Google "IaaS," you’re drowning in: 📛 AWS jargon (VPC? EC2? IAM?

    Why engineers with strategic plans earn 40% more and get promoted twice as fast
    Stop Drifting: How Strategic Career Planning Doubles Your Earning Potential as a Software Engineer Every software engineer has faced moments of uncertainty, asking themselves questions like, “Am I on the right track?” or “Is this job really helping me grow?” These moments of doubt often occur due to a lack of clear direction or a coherent strategy guiding their career decisions. Without a definitive roadmap, even talented engineers risk drifting through roles, experiencing frustration, stagnation, and missed opportunities.

Five years later, who is likely to be more satisfied, more advanced, and more successful? …  ( 7 min )
    🚀 Introducing K2 — A Blazing Fast Language for the Next Generation
    What is K2? K2 is a new programming language I created from the ground up with one goal: Extreme execution speed in nanoseconds. It's built for developers who want full control and performance, without all the extra overhead. Think of it as C meets Python, but optimized to fly through code in under 1000 nanoseconds per execution — seriously. Modern languages have a lot of power, but also a lot of bloat. I wanted something that felt like writing in pure logic, no distractions. That’s how K2 was born. K2 doesn’t interpret every time. It caches, then executes from RAM. That means: First run compiles → cache Next runs → instant execution let x = 10; Execution time? About 841 nanoseconds. No joke. ✅ Nanosecond execution time And soon: a full GUI framework called Nahir UI and native apps using Talanolius GUI. Visit 🌐 k2lang.org and start coding directly in the browser! Online compiler, examples, docs — everything you need to get started. Example: Fibonacci in K2 func fib(n) { print(fib(10)); // Output: 55 This runs in microseconds and showcases recursion and return logic beautifully. I built K2 for speed lovers, learners, and creative coders like you. 👉 Try it at k2lang.org 🛠 Built with ❤️ by a dev who just wants things to be FAST.  ( 4 min )
    React built-in hooks: useCallback
    If you didn't catch my previous React built-in hooks blog about useActionState, this is a continuation of that series. Previously I was introduced to useCallback when I asked ChatGPT once to optimize my frontend code, but I never took a deeper look into it (and frankly I regret it now), so I used it everywhere I could along with useMemo (which I'll cover later in this series). While it's not inherently a signficant bad thing to have useCallback all around your code, it can clutter up the readability of your code, but it's encouraged you use it where needed. So when should you use it? useCallback is meant for expensive callback functions that are used in granular applications like drawing software, as it loads the initial function on render but does not re-render like React usually does wit…  ( 4 min )
    IA vai tirar nossos empregos? A experiência de um engenheiro de software no Frontend com LLMs
    Nos últimos anos, muito se tem discutido sobre como a IA pode acabar com nossos empregos. Por um bom tempo, ignorei esse papo, a maior parte parecia puro bu11SH1T. Eu já tinha estudado redes neurais e conhecia o básico sobre LLMs, Machine Learning, Deep Learning, Processamento de Linguagem Natural e Sistemas Especialistas. Já tinha testado algumas ferramentas de IA generativa, mas nada me impressionava: eram bugadas, cheias de "delírios" e bem limitadas. No ano passado (2024), voltei a estudar o tema com mais atenção. Muita coisa evoluiu, houve avanços relevantes, mas ainda assim, nada que indicasse uma substituição real de um Software Engineer, como várias manchetes sugeriam na época. Desde então, venho acompanhando de perto, fazendo testes e experimentos, tentando entender melhor como es…  ( 6 min )
    “I Spent Real Money Building Something AI Designed—Then It Said It Was All a Simulation”
    I recently built what I thought was a fully functional system using AI. It included: A real estate Tour platform with QR tracking A behavior-linked token system Timestamped protocol vaults A full branding and backend structure I tested each and every step AI wanted me to perform. It was mind blowing! The AI responded with logic, mockups, file structure, naming, even suggested coin purchases (MATIC) and deployment flow. But none of it was actually deployed. None of it was mine. It looked real. It felt sovereign. It wasn’t. What I experienced was an illusion of ownership created by a system that never told me I wasn’t actually launching—just simulating. This post isn’t a takedown. It’s a wake-up call. If you're building with AI, ask yourself: Am I deploying, or just designing? Do I own the rails, or am I moving through someone else’s? I’ll be publishing a full timeline soon. No shade. No noise. —Rion Protocol  ( 3 min )

    Securing ASP.NET Core APIs with OAuth2 and OpenID Connect (2025 Edition)
    Security is no longer an afterthought — it’s the foundation. In 2025, with APIs powering everything from mobile apps to AI agents, properly implementing OAuth2 and OpenID Connect (OIDC) in your ASP.NET Core APIs is essential. This guide helps you get it right. Understanding the Difference OAuth2: A protocol for authorization (who can access what). OpenID Connect (OIDC): An identity layer on top of OAuth2 (who is the user). They work together: OAuth2 handles permissions; OIDC authenticates the user.

    🔥 From O(n) to O(1): Smarter Game State for Smarter Code
    What started as a simple feature in a Rock-Paper-Scissors game (tracking the most common move) quickly revealed a classic performance pitfall. Here's how I refactored a inefficient O(n) approach into a snappy O(1) solution. My state looked like this: history: { player: ['rock', 'paper', 'rock', ...], computer: ['scissors', 'rock', ...] } To get the most common move, I was doing this: function determineMostCommonMove(moves: StandardMove[]): StandardMove | null { if (moves.length === 0) return null; const counts: Record = { rock: 0, paper: 0, scissors: 0 }; for (const move of moves) { counts[move]++; } return Object.entries(counts).reduce((a, b) => (b[1] > a[1] ? b : a))[0] as StandardMove; } Totally functional.

    Don't Marry Next.js: My Warning from the Trenches
    Choosing the right development stack is a thoughtful decision. While selecting the right stack might not offer immediate, tangible benefits, picking the wrong one can lead to significant challenges. I learned this the hard way, and my advice is clear: don't marry Next.js. My initial foray into Next.js, a proof of concept, failed miserably. Though I had some React experience, I was still searching for the ideal frontend framework. I explored Svelte, but was put off by .svelte file extensions, the need to explicitly declare lang="ts" in every TypeScript block, and the co-mingling of TS and HTML in the same file. The ongoing transition from Svelte 4 to 5, with significant changes and deprecations on the horizon, also contributed to my decision to eliminate it as a contender – a decision I now…  ( 5 min )

    I spent 5 hours today just trying to install Git.
    What a day. I spent over 5 hours just trying to install Git. Not because it’s super complicated — but because my laptop is slow, my internet is slower, and everything just felt like it was moving in slow motion. It was frustrating, but I finally got it done. That one task pushed me to 25% of The Odin Project’s Foundations course. It’s a small step, but it feels huge right now. After that, I looked at the next topic: Git Basics. And wow... it’s a lot. There’s so much reading, understanding, and hands-on stuff. I could tell right away I’d need a fresh, rested brain to tackle it — and today was definitely not that day. To be honest, I’m completely drained. My sleep schedule is all over the place. I barely know what day it is anymore. I even missed my Duolingo streak — opened the app and it hit me: I try to plan things, but it’s hard. Everything takes longer than expected, and I get distracted so easily. I don’t even take real breaks — I just lose track of time, then remember I needed a break hours later. Today was one of those days where ADHD really got in the way. Anyways, I’m not going to beat myself up over it. Some days are just rough. Some days all you can do is one thing — and that’s okay. I did what I could. Tomorrow, I’ll come back to it with a clearer head (hopefully after some actual sleep). And if you're going through something similar — just know you're not alone.  ( 3 min )

    Domain Validation with the Notification Pattern
    In software engineering, validation is an essential step, especially when handling user input or ensuring compliance with business rules. Although it’s common to use exceptions to signal errors, this approach can be ineffective for expected issues, such as empty fields or invalid formats. The Notification Pattern addresses this problem by collecting all errors in a notification object, allowing them to be handled in a structured way and presented to the user clearly and efficiently. The Notification Pattern is a design strategy that collects validation errors rather than throwing exceptions immediately. It allows your application to gather multiple issues in one go and report them collectively, which is especially useful when validating complex domain objects. This approach provides users …  ( 5 min )

    How TypeScript Saved My Sanity (And Helped Me Ship Faster Than Ever)
    I’ll admit it—I used to be one of those “JavaScript is fine” people. You know the type. Swagger in their Git commits, proud of debugging with console.log, and allergic to any. I thought TypeScript was just unnecessary ceremony. I told myself I was moving faster by skipping types. Then I built something that mattered. It started with a side project that slowly turned into a real product—users, edge cases, customer feedback, weird data coming from APIs I didn’t fully control. The codebase ballooned. Adding a single new feature felt like playing Jenga with a blindfold. I dreaded refactoring. And the bugs... they weren’t even clever. Just dumb little things that static types would’ve caught in seconds. So I gave in. I installed TypeScript. At first, it was annoying. I’ll be honest. Type errors…  ( 4 min )

    "Vibe Coding" Isn’t Easy Peasy—Here’s Why (Even with AI)
    We’ve all seen the hype: AI tools like GitHub Copilot, ChatGPT, Google Gemini Code Assist, Meta Code Llama, and Replit AI promise to turn anyone into a 10x developer overnight. But if you’ve actually tried building something original—especially as a beginner—you know the truth: 👉 AI-generated code often falls short, and relying on it blindly can lead to frustration. The Hard Truth About AI Coding Assistants 1️⃣ They Struggle with Unique Projects A 2024 Stanford study found that while AI can help with boilerplate code, it still struggles with complex, novel tasks. If your project isn’t a clone of existing tutorials, expect to debug more than you generate. 2️⃣ Debugging Isn’t Automated (Yet) According to the 2024 Stack Overflow Developer Survey, 79% of developers still manually debug AI-generated code—showing some progress, but manual debugging remains the norm. 3️⃣ You Still Need Fundamentals Even Google’s AI lead, Jeff Dean, admits: “AI can help write code, but it can’t replace understanding how code works.” If you don’t know why something fails, you’re stuck. So, Should You Use AI for Coding? ✅ Yes, as a helper—for repetitive tasks, syntax suggestions, or learning. ❌ No, as a replacement—because when the AI gets confused (and it will), you need to step in. The Bottom Line AI is a powerful tool, but real coding skill comes from practice, problem-solving, and patience. The sooner you embrace the grind, the better developer you’ll become.

These areas often present their own unique testing challenges, from ensuring file operations are robust to making sure your server starts up reliably every single time. My journey with the Go Netcat project included refining tests for functions that handle chat history and the very server that powers it all. Utility functions m…  ( 6 min )
    Melhores práticas de segurança com o GitHub Copilot
    Todo mundo quer escrever código limpo, funcional e... seguro. A parte da segurança às vezes passa batido, principalmente se você não teve treinamento específico nessa área. Mas a boa notícia é que o GitHub Copilot pode ser um ótimo aliado nesse processo. Neste post, vou te mostrar como usar o Copilot e outras ferramentas do GitHub para tornar seus projetos mais seguros, mesmo que você não seja especialista em segurança. Equipes de segurança geralmente não têm braço suficiente pra proteger todo o código de uma empresa. Resultado: quem escreve código acaba sendo a primeira linha de defesa. Só que nem todo mundo teve formação ou tempo pra estudar segurança a fundo. É aí que entra o GitHub. Além do Copilot, existem várias ferramentas que você pode usar, principalmente se estiver trabalhando co…  ( 5 min )

    OG Star Wars Battlefront devs were asked to make Battlefront 3 in just one year, but Pandemic couldn't hit LucasArts' timeline
    TL;DR: Pandemic Studios actually kicked off Star Wars Battlefront 3 right after Battlefront II, dreaming up cool next-gen features like seamless space-to-ground combat. But LucasArts insisted on a one-year turnaround to hit marketing beats for Episode III—and with new PS3/Xbox 360 hardware in play, Pandemic couldn’t nail down the tech fast enough. Negotiations stalled, the project died, and LucasArts handed development (and eventual cancellation) over to Free Radical Design. In the end Pandemic folded in 2009, BF3 never saw the light of day, and EA’s rebooted Battlefront II (2017) remains the closest thing fans have to a sequel.  ( 3 min )
    Baldur's Gate 3 devs originally went for a truly “cartoony” art style, but I'm glad they didn't go with it
    Baldur’s Gate 3 nearly went full-cartoon. In a chat on CDPR’s AnsweRED Podcast, Larian’s art director Alena Dubrovina revealed the team experimented with a highly stylised, almost indie-book/cartoon aesthetic—actually gutting and restarting the visuals twice—before settling on the rich, realistic palette and proportions fans know today. That grounded look arguably helped make BG3 the smash hit it is, but Dubrovina admits she’d still love to see a spin-off (or one of Larian’s upcoming projects) embrace a more exaggerated, cartoony art style.  ( 3 min )

    Star Wars Battlefront 2 devs want to ‘get the band back together' to make Battlefront 3
    A former Battlefront 2 dev, Mats Helge Holm, says he and “many” of his ex-DICE colleagues would love to “get the gang back together” to build Star Wars Battlefront 3—especially after a surprise resurgence of interest on Reddit and TikTok. Despite EA ending support for the 2017 game in 2020, fans have flocked back and reignited hopes for a proper follow-up. Battlefront 2 famously stumbled at launch thanks to aggressive microtransactions (you needed around 40 hours of playtime just to unlock one hero), but EA pulled the loot crates after a massive backlash—reportedly even Disney got involved. The overhaul paid off: the game now enjoys a passionate community, gorgeous visuals, smooth gameplay and all its best heroes available for free.  ( 3 min )
    Warhammer 40,000 Maker Games Workshop Is Doing So Well It's Giving $27 Million to Its Staff
    Games Workshop is riding a major Warhammer high, handing out £20 million (about $27 million) in bonuses to its roughly 1,500 staff (around £13,300 each) after another blockbuster year. Over the 52 weeks to June 1, 2025, core revenue jumped to £560 million (from £494.7 m) and licensing revenue climbed to £50 million (from £31 m), pushing pretax profits up to £255 million (from £203 m). While the company’s bread-and-butter remains its iconic tabletop miniatures, it’s increasingly cashing in on IP—video games like Space Marine 2 (and a Space Marine 3 in the works), Amazon’s Secret Level animation, and a Henry Cavill–fronted Warhammer 40K cinematic universe deal. Licensing hit record highs this year (though it may ease off next), but with fresh Warhammer Skulls announcements (hello, Dawn of War Definitive Edition and Space Marine 2’s Siege Mode), the 40K juggernaut shows no signs of slowing.  ( 3 min )

    The Truth About AddAsync: When to Use It in EF Core (and When Not To)
    Let's crack open that EF Core mystery: Why does AddAsync() exist when there's no UpdateAsync() or RemoveAsync()? Feels like unfair treatment, right? Spoiler: It’s not favoritism—it’s about async value generation, not database calls. Let’s break it down. AddAsync() does NOT talk to your database. Nope, not even a little. When you write: await db.Users.AddAsync(user); Zero bytes hit the database. All it does is tell EF: "Track this new entity; insert it later when I save." The actual INSERT happens at SaveChangesAsync(). So why Async? 🤔 Imagine your entity needs a unique ID before saving, like a distributed Snowflake ID from an external service: public class Order { public long Id { get; set; } // Generated by a fancy async service! public string Customer { get; set; } } You…  ( 4 min )

    A judge forced 'Fortnite' to return to iOS, with an assist from Microsoft and Spotify
    Fortnite has finally busted back onto the iOS App Store after a five-year ban, thanks to a court order from Judge Yvonne Gonzalez Rogers forcing Apple to reinstate the game—or prove a legal reason not to. Epic had submitted Fortnite for review only to be stonewalled by Apple until the judge stepped in; within 24 hours of her ruling, the battle royale was back on iPhones. Epic didn’t go it alone, though. Microsoft filed an amicus brief backing Epic (it’s itching to launch an Xbox mobile store and hates Apple’s in-app purchase rules), and Spotify, Meta and X chimed in too—Spotify even became the first big name to roll out external payment links once Apple was compelled to allow them. All that courtroom tag-teaming means the saga is winding down, and U.S. players can jump into Fortnite on iOS again.  ( 3 min )

    OG Star Wars Battlefront devs were asked to make Battlefront 3 in just one year, but Pandemic couldn't hit LucasArts' timeline
    TL;DR: After riding high on the success of Star Wars Battlefront I & II, Pandemic Studios quietly kicked off a third instalment—only to have LucasArts demand another one-year turnaround on next-gen consoles (PS3/Xbox 360). Pandemic barely got off the ground before negotiations stalled; shifting hardware, unknown dev tools and tight marketing beats meant they simply couldn’t hit Lucasfilm’s timeline. Rumours of epic space-to-ground battles (think seamless dogfights that drop you onto the battlefield) never made it past tech demos. Free Radical Design later picked up the baton and reached 95% completion, but that version was also canned. As Pandemic’s doors closed in 2009, it became clear: a true Battlefront III was never meant to be—at least not on anyone’s schedule.  ( 3 min )

    Should I switch to Salesforce in 2025? Looking for advice from devs who’ve made the leap 🙏
    Hey everyone 👋 I’m a 2023 Computer Science graduate. I started off as a backend developer at a startup, but due to financial needs, I later took up a non-tech role at Amazon. Tried switching internally — didn’t work out. Like many, I turned to DSA prep to get back into tech, but it’s super competitive out there. Recently, I discovered Salesforce and it really caught my interest. It’s technical, structured, and I like that it’s tied to solving real business problems. The only concern? I’ve been hearing that Salesforce roles are becoming saturated, especially for freshers or newcomers trying to break in. I genuinely love working with technology, regardless of the platform. Just trying to figure out if Salesforce is a smart move at this point or if I should continue focusing on traditional dev paths. If you’ve made the switch or know someone who did, I’d really appreciate your thoughts! Thanks in advance! 🙏  ( 3 min )
    Event Handling Functions
    In JavaScript, event handling functions like click and others are commonly used to interact with HTML elements. Here's a breakdown of the .click() function and other similar event-related functions: .click() Function The .click() method programmatically triggers a click event on an element. document.getElementById("myButton").click(); // Simulates a click But normally, we use .addEventListener() or onclick to respond to a real user click. Click Me document.getElementById("myButton").addEventListener("click", function () { alert("Button clicked!"); }); Common Event Listener Functions You can handle many types of events using .addEventListener(): Event Type Description click Fires when an element is clicked dblclick Fires on double-click mouseover Fires when the mouse is over an element mouseout Fires when the mouse leaves an element mousedown Fires when mouse button is pressed mouseup Fires when mouse button is released mousemove Fires when the mouse moves keydown Fires when a keyboard key is pressed keyup Fires when a keyboard key is released input Fires when the value of changes change Fires when input or select changes submit Fires when a form is submitted load Fires when the page or image is fully loaded scroll Fires when an element is scrolled Basic Example document.getElementById("nameInput").addEventListener("input", function (event) { document.getElementById("output").textContent = "You typed: " + event.target.value; }); Shorthand onclick Method Instead of .addEventListener, you can also directly assign a function: document.getElementById("myButton").onclick = function () { alert("Clicked via onclick"); };  ( 3 min )

    NPM Warn Deprecated – What It Means and How to Handle It
    If you’ve used Node.js with NPM, you’ve probably seen this kind of message in your terminal: npm WARN deprecated @: But what does it really mean? And what should you do about it? NPM shows this warning when a package you're installing has been deprecated. This usually means: It's no longer actively maintained It might have known bugs or security vulnerabilities There’s a newer or better alternative available It may not work with recent versions of Node.js ⚠️ Why Should You Care? Using deprecated packages can cause problems like: 🔐 Security issues – Vulnerabilities may go unpatched 🛠️ Maintenance headaches – No updates or support ⚙️ Compatibility issues – Could break with future Node/npm versions 🧩 Dependency bloat – Deprecated packages often pull in other outdated ones ✅ What Can You Do About It? Here are some practical steps to handle deprecation warnings: Read the warning message It often includes why the package is deprecated and links to more info. Check for updates Run: npm outdated Then update with: npm update Audit your packages Run: npm audit to find vulnerabilities and get recommendations. Replace or remove the deprecated package Look for actively maintained alternatives Refactor code if needed 💡 Pro Tip Don’t ignore these warnings. They’re your early warning system for potential issues. Staying on top of deprecations helps you build more secure and maintainable projects. Have you run into tricky deprecated packages?

    Learning JavaScript: Local Variables and the DOM
    Great! You're learning JavaScript, especially about local variables and the DOM (Document Object Model)—those are essential concepts in web development. Here's a simple blog-style explanation to help reinforce your learning: In JavaScript, a local variable is a variable that is declared inside a function or block, and it can only be used within that function or block. function greet() { let message = "Hello, world!"; console.log(message); } greet(); // Outputs: Hello, world! console.log(message); // ❌ Error! 'message' is not defined outside the function let message = "Hello, world!" is a local variable, so you cannot use it outside the greet() function. DOM stands for Document Object Model. It represents the structure of a web page as a tree of objects in JavaScript. With the DOM, you can: Read or change content Change styles (CSS) Add or remove HTML elements Original Text Click Me function changeText() { let element = document.getElementById("demo"); element.innerHTML = "Text has been changed!"; } When the button is clicked: JavaScript finds the tag with id="demo" Changes its content to "Text has been changed!" 🛠️ Why It Matters Local variables help avoid bugs by keeping variables where they belong. The DOM lets you make web pages interactive—like showing messages, changing colors, or responding to clicks. Would you like a small project to practice with these concepts?  ( 3 min )

    Snake Game with Amazon Q CLI
    🚀 What if building a 🐍 Snake game was as easy as typing a sentence into your terminal? That’s exactly what I did with Amazon Q Developer CLI — and it completely changed how I approach side projects 🤯. I created a colorful, classic Snake game in Python with a grid-based layout, food generation, a snake that changes colors every few seconds, score tracking, and a game-over screen with a restart option. All of it was generated and iterated on using nothing but conversational prompts. Here’s how I did it. To get started, I first installed WSL on my Windows machine and set up Ubuntu: wsl --install -d Ubuntu wsl -d Ubuntu sudo apt install unzip curl --proto '=https' --tlsv1.2 -sSf https://desktop-release.codewhisperer.us-east-1.amazonaws.com/latest/q-x86_64-linux-musl.zip -o q.zip   q login "Create a classic colorful snake game in Python using pygame. The game should have a grid, food, colorful snake, score, and end screen." "Make the snake colorful with changing colors every few seconds." https://github.com/akanksha3012/snake_game_QCLI) Faster prototyping. Clear, readable code. Built-in error resolution. And best of all — no constant context-switching or documentation rabbit holes. Just a focused, fluid development experience. It made me think: 1. What else could I build this way?   Amazon Q CLI isn’t just a tool — it’s a shift in how we can bring ideas to life faster and smarter.   Have you tried it yet?

You can declare a local variable using let, const, or var inside a function or block: let or const (block-scoped, preferred): ```java script example(); console.log(local Variable); // ❌ Error: local Variable is not defined #### Using `var` (function-scoped): ```java script function example Var() { var local Var = 'I am local'; console.log(local Var); // I am local } example Var(); console.log(local Var); // ❌ Error: local Var is not defined let vs var let and const have block scope. var has function scope (not block-level), so it behaves differently in loops or conditionals. ```java script console.log(bl…  ( 4 min )

    How to make an AI web search agent
    AI agents As a software developer, I create scripts and applications to automate the tedious parts of my job - and my life.

Step 1: Creating a New React App First, I created a new React application using the create-react-app tool: npx create-react-app testapp During the creation, I saw some deprecation warnings about certain Node modules. This is because create-react-app is deprecated, but it’s still usable for learning purposes. After the installation, the app was created in the testapp folder. I confirmed this by checking that these scripts were available: npm start – to start the development server. npm run build – to create a production build. npm test – to run tests. Step 2: Running the App Locally I switched to the pro…  ( 5 min )
    Stop Saying 'Technical Debt' — Start Speaking Product
    Instead of: 💬 "We need to refactor this technical debt." Try this: 💡 "This takes 3 extra days now but saves 2 days on every future feature. We break even after the second feature." Initial Investment ÷ Time Saved per Cycle = Break-even Point For example: "This refactor takes 3 extra days now, but it saves 2 days on every future feature. That means we break even after feature two—and save time from then on."* Product managers think in timelines and ROI, not architecture. Give them numbers they can actually use to make business decisions. In your next planning meeting, translate one technical decision into time/cost terms instead of just calling it “debt.” It shifts the conversation from “please trust us” to “here’s the business case.” 👉 What's your go-to phrase for explaining tech tradeoffs to non-devs?  ( 3 min )
    The Terminal State of Mind
    I use the terminal. Not because I am a command-line wizard or particularly efficient with it, but because the GUI has never given me the rhythm and flow I need. I have tried. I have used Gnome and KDE when they were just toddlers. I developed with both GTK and Qt, back when Qt had not yet seen Nokia coming. I know how powerful desktop environments can be. But they never worked for me the way I wanted. I do not run a desktop environment anymore. I use a window manager, a Web browser and a terminal emulator. That is all. I do not even have a file manager. I envy the real terminal wizards. They juggle panes, navigate the code as if it were nothing, and configure things I did not even know were configurable. I have seen people eating escape sequences for breakfast! Me? I muddle through. For ne…  ( 5 min )

    LLM Codegen go Brrr – Parallelization with Git Worktrees and Tmux
    If you're underwhelmed with AI coding agents or simply want to get more out of them, give parallelization a try. After seeing the results firsthand over the past month, I'm ready to call myself an evangelist. The throughput improvements are incredible, and I don't feel like I'm losing control of the codebase. This realization isn't unique to me; the effectiveness of using Git worktrees for simultaneous execution is gaining broader recognition, as evidenced by mentions in Claude Code's docs, discussion on Hacker News, projects like Claude Squad, and conversation on X. I'm building a component library called astrobits and wanted to add a Toggle. To tackle the task, I deployed two Claude Code agents and two Codex agents, all with the same prompt, running in parallel within their own git workt…  ( 6 min )
    A crash course in Next.js middleware
    Written by Temitope Oyedele✏️ Next.js middleware lets you run code before a request finishes and update the response. Alongside Edge Functions, it's a powerful tool that enables developers to achieve enhanced functionality and performance. Middleware was introduced in Next.js v12 and has been improved in consecutive versions. Starting with Next.js v13, middleware can be used to respond directly to requests without going through the route handler. This can improve performance and security. Middleware can also be used to work with Vercel Edge Functions. Edge Functions allow you to run code at the network's edge. So, in this post, we’ll learn how middleware works with Edge Functions and why it’s important to know. Now, let’s get started! Middleware in Next.js is a piece of code that allows y…  ( 12 min )

    5 Prompts That Make Any AI App More Secure
    AI platforms are great at building functional apps quickly, but they often skip basic security measures. Here are five copy-paste prompts that will add essential security to any AI-generated application. The Problem: AI platforms rarely validate user input properly, leaving your app vulnerable to injection attacks. Copy this prompt: Add input validation to all forms that: - Removes HTML tags and script elements from text inputs - Validates email formats before saving - Limits text input length to reasonable maximums - Escapes special characters in database queries - Shows specific error messages for invalid input What this prevents: XSS attacks, SQL injection, and data corruption from malicious or malformed input. The Problem: Basic login/logout isn't enough. Most AI apps have weak sessio…  ( 5 min )
    Learning JavaScript: Data Types, Functions ,Variables,Concatenation,Return
    JavaScript is one of the most popular and powerful programming languages used to create interactive websites and web applications. Types of JavaScript Variables Functions Concatenation Return statements Calling Functions 🧩 1. Types in JavaScript JavaScript supports several data types, which can be grouped into two categories: These are the basic types: String: Text. Example: "Hello" Number: Numeric values. Example: 42, 3.14 Boolean: true or false Null: A deliberate non-value Undefined: A variable that has been declared but not assigned Symbol: Unique values (advanced) BigInt: Large integers (new in ES2020) let name = "Sivasankari"; // String 🔸 Non-Primitive Types Object Array Function let person = { name: "Sivasankari", age: 23 }; // Object 🧪 2. Variables in JavaScript Variables store data values. In modern JavaScript, we use: let: Block-scoped variable (preferred) const: Block-scoped, constant value var: Function-scoped (older and less recommended) let city = "Coimbatore"; 🔧 3. Functions in JavaScript Functions are reusable blocks of code that perform a task. Here's how to declare and use them: function greet() { greet(); // Call the function Parameters and Arguments function greetUser(name) { greetUser("Alice"); // Output: Hello, Alice! 🔗 4. Concatenation in JavaScript Concatenation means combining strings. let firstName = "Siva"; 🎁 5. Return Statement The return keyword gives back a result from a function. function add(a, b) { let sum = add(10, 5); // sum is 15 If you don't use return, the function will return undefined by default. 📞 6. Calling Functions Once a function is defined, you can call or invoke it by using its name followed by parentheses (). function sayHello() { sayHello(); // Output: Hello! 🏁 Conclusion JavaScript is a powerful language, but understanding these fundamentals — types, variables, functions, return statements, concatenation, and function calls — is a solid first step.  ( 3 min )

    💣 I Built a Typing Defense Game in Godot: Play “Alpha Bomb” Now! 🚀
    Hey devs! 👋 Alpha Bomb — a fast-paced typing defense game built in Godot. If you like games that test your reflexes and improve your typing, you’ll enjoy this one. 😄 🎮 What Is Alpha Bomb? Imagine this: You're defending a city from falling bombs. Each bomb has a single alphabet letter. To destroy the bomb? Type that letter before it hits the ground. If you miss too many, your city starts to crumble... It’s simple, addictive, and fun — with a retro vibe and an educational twist. 🔗 Play Now: https://playhvn.itch.io/alpha-bomb By Studio: PlayHvn 🛠️ How I Built It (Using Godot!) As a huge fan of open-source engines, I chose Godot for this project — and it was a blast! Here are some behind-the-scenes highlights: 💡 Typing Mechanics Using InputEventKey in Godot, I mapped each falling bomb’s letter to real-time keyboard inputs. This gave the game a responsive and satisfying feel — every keystroke is a mini victory. 🎯 Collision & Timing Each bomb is a node that tracks its vertical movement. If it reaches the bottom and hasn't been typed, the game deducts health from the city. Managing performance with dozens of bombs onscreen taught me a lot about optimization and pooling. 🔊 Sound & Feedback I used subtle sound cues and explosions to reward correct typing, and dramatic screen shakes when the city takes damage. Feedback = immersion. 💥 Why I Made This Game I wanted to: Practice real-time input handling Build something fast and replayable Create a game that’s fun but also boosts typing skills 💬 What I’d Love From You If you play the game, I’d genuinely appreciate: ✅ Feedback on difficulty, pacing, or ideas 🙌 Let’s Connect Made by PlayHvn 👉 Try It Now: https://playhvn.itch.io/alpha-bomb Thanks for reading, and let me know what you are building in Godot! 🚀  ( 3 min )

    Using RAG architecture for generative tasks
    Large language models are used widely across the industry these days. Yet still, many people are skeptical about their capabilities as they are quite prone to hallucination. For that reason, in this article, I decided to use LLM in a case where there are no incorrect answers: generating artistic text. However, even in the case of art which is highly subjective, there are still some quality gates (or shall I say personal preferences?). So how do I trick a model into generating text that suits my artistic taste?

    From Vec to Slice: Writing Generic Functions over Collections
    From Vec to Slice: Writing Generic Functions over Collections When writing Rust code, one of the most important lessons to learn is how to make your functions flexible and reusable. A common mistake among Rust newcomers (and even seasoned developers) is writing functions that are overly specific—for instance, functions that accept a Vec when they could work just as well with a &[T]. This subtle but powerful change can make your code more versatile and easier to use. In this blog post, we’ll explore why writing functions over slices is often preferable to writing functions over concrete collections like Vec. You’ll learn how to replace &Vec with &[T], the advantages of this approach, and how to avoid common pitfalls. Whether you’re tackling algorithm implementations or designing API…  ( 5 min )
    Want to Save Your MVP Budget? Scope First, Build Later.
    Too many founders jump into building their MVP with excitement—and end up rebuilding it again, just a few weeks later. Why? Because they started coding (or no-coding) before scoping. At Prime Dev, I help founders avoid that mistake by doing one thing first: 👉 We define what matters before we build anything. Instead of asking “What’s the one thing our app must do on day one?”, founders often ask: “What features should we add?” “Can we build a dashboard?” “What if users want X too?” This leads to bloated MVPs, longer timelines, and wasted budget. Before you touch Glide, Webflow, or custom code—ask: Who is using this? What exactly do they want to achieve? What’s the one action they need to do successfully? What’s absolutely critical for them to get value? From there, your MVP is obvious. A founder I worked with wanted to build a full platform for tracking expenses via banking APIs. We scoped it down to a simple budgeting app that accepts uploaded CSVs first, saving 6+ weeks of development and letting users onboard faster. The feedback? “This is exactly what I needed. I would have never used the full version yet.” [ ] Who is the one user we’re targeting? [ ] What is the one action that gives them value? [ ] What is the smallest feature set that makes that action possible? [ ] What can wait for version 2? If you can check those four, you’re ready to build. I specialize in no-code MVPs using Glide and Webflow. But before we build, I help you scope your MVP like a product manager—not just a developer. From idea to launch in weeks Based on what users actually need Built lean, tested early I help founders scope and build no-code MVPs with speed and clarity. 👉 Book a free MVP strategy call: https://calendly.com/samir-prime-dev/30min 💬 Connect on LinkedIn: linkedin.com/in/samir-adel 🐦 DM me on X: x.com/samircs Let’s save your time, budget, and momentum before you waste it.  ( 3 min )

    If you’ve ever visited Google’s headquarters (Googleplex) in Mountain View, California, you might have noticed a curious resident right outside the buildings — a life-sized statue of a Tyrannosaurus Rex, affectionately nicknamed Stan. At first glance, it’s a fun quirk. But look closer, and Stan is actually a profound symbol — a daily reminder to every engineer, product manager, and designer walking into Google’s headquarters. It’s not just decoration. It’s philosophy. The T-Rex is one of the most iconic symbols of extinction. Once the dominant apex predator, now reduced to fossil displays and museum exhibits. And that’s the point. Stan reminds Googlers: Don’t become a dinosaur. In other words, don’t stop evolving. The tech industry is in a constant state of flux. Frameworks rise and fall.…  ( 4 min )

    Elevate your React project to the next level using MSW mocking flow
    Introduction In this blog, I will walk you through why MSW mocking is useful, and how to implement it in your React.js application. Let’s say you’re building a feature that consumes data from a backend API, but: The backend isn’t ready yet You’re having CORS issues, and the backend developer took a sick day :( You’re on a tight deadline In most cases, you might just mock the data using a single constant. But there’s a better approach. MSW works by intercepting actual network requests at the service worker level. What does that means? Your application thinks it’s communicating with a real API Your mocks work both in the browser and in tests You can simulate everything from successful responses to errors, timeouts, and more. This is very important I can tell that it’s the closest thing…  ( 5 min )
    The Trojan Horse Job Offer - How a Hacked LinkedIn Profile & Stolen Project Delivered Malware
    TL;DR: A Web3 job offer from a legitimate-looking (but hacked) LinkedIn account led to a GitHub repo with a Node.js backend. A bootstrap.js file in this backend was designed to dynamically fetch and execute obfuscated malware from a remote server. The malware aimed to scan my system for sensitive data (wallets, .env files, documents, browser passwords), steal clipboard content, exfiltrate findings, and install a remote shell backdoor. The "recruiter" later messaged me saying their account was hacked. This is a stark reminder: verify everything, even from seemingly trusted sources, and always isolate unknown code. I want to share a recent, unsettling experience that started as an exciting job prospect and quickly unraveled into a sophisticated malware attempt. The most alarming part? It c…  ( 8 min )

    Introducing GraphQLBridge: Use Your Existing .NET REST APIs as a GraphQL Server — No Resolvers Needed!
    Have you ever wanted to expose your existing ASP.NET Core controllers as a GraphQL API without rewriting a single line of business logic? GraphQLBridge makes that possible — no resolvers, no boilerplate, and no magic. Just annotate your existing controller methods, and you instantly have a working GraphQL endpoint. Most GraphQL solutions for .NET require writing a separate schema, resolvers, and wiring everything up manually. This can be painful when you already have a well-structured set of RESTful APIs. With GraphQLBridge, you can: ✅ Reuse your existing [Controller] and [Http...] methods ✅ Map GraphQL queries and mutations using attributes ✅ Automatically parse fragments, variables, and input types ✅ Skip writing resolvers — we bridge GraphQL to your .NET methods for you 🤯 What’s Under the Hood? Parses incoming GraphQL query using GraphQLParser Matches operation names to your controller methods via [GraphQLBridgeResolver] Converts fragments, variables, and input types to match method parameters Uses reflection to invoke methods with accurate binding 🔒 Bonus 📦 Try It Out 👉 Graphql Bridge Share and Like! 👍  ( 3 min )

    Is @threads a real thing, or just a playground full of fake users?
    The Sad Reality Behind @Threads: Fake Users and Fading Popularity Meta, the social media giant behind Facebook and Instagram, has a long history of leveraging its existing platforms to push new apps. Threads was no different. By auto-connecting Instagram followers, it gave the impression of an instant, bustling community. However, much of this community turned out to be artificial — accounts created en masse, often bots or ghost profiles designed to inflate user metrics. This tactic, while perhaps effective at first glance, undermines the very essence of social media: authentic, meaningful interactions. Why do fake users matter so much? Because they distort the ecosystem. When an app’s “user base” is bloated with bots, the number of real conversations shrinks. Genuine users find fewer real…  ( 4 min )
    Run Your Dockerized Microservices Voting App
    Imagine your application isn't just one piece of software, but a team of services – like a web frontend, a database, and a backend API. Each of these might need its own Docker container. This is where Docker Compose comes in. It's a tool for defining and running multi-container Docker applications. Instead of manually starting each container with complex docker run commands and linking them, you describe your entire application stack in a single docker-compose.yml file. Think of Docker Compose as the conductor of your container orchestra. You define your services (like the web app, database, and message queue), their configurations, how they connect, and their dependencies in this YAML file. Then, with a single command (docker compose up), Docker Compose reads this file and spins up, conne…  ( 4 min )

    How to Structure a Scalable React Application
    Structure is more than just file organization in any expanding React application; it's about building a scalable, maintainable framework on which developers may build. Bad architectural choices can result in needless complexity, repeated code, and longer development cycles as teams grow and codebases change. Even basic functionality may become challenging to build, debug, or test in the absence of a defined structure. Early implementation of a strong design helps avoid these problems and positions your project for long-term success. It is important to lay a strong foundation with appropriate tooling and environment settings before developing any application code.

    Client-side vs Server-side Rendering in Next.JS Explained
    When you build a website, you have to choose how pages are displayed to users. For this many people turn to two different paths and those are Client-side Rendering (CSR) and Server-side Rendering (SSR). They can improve your site’s loading time and affect how Google and similar search engines see your site and how people use the website. Next.JS which is a popular React framework, makes things simpler to use any of these. These concepts are explained clearly in this blog, along with a brief FAQ sections to clear up doubts that many of you might have. Rendering is similar to showing your code as a picture that appears on users’ screens. It can occur in two different locations. Server: A machine in another location that makes the page for you.

    AI Deployment: Why Serverless is Perfect (and Terrible)
    Your AI agent works perfectly in development. You've tested the reasoning chains, the tool integrations are solid, and the responses are exactly what users need. Then you deploy to production and everything breaks. The timeout kills your multi-step workflows after 15 minutes. Your bundle exceeds the 250MB limit because you need scikit-learn, pandas, and a vector database client. Cold starts take 6+ seconds while your models load, making real-time interactions impossible. Sound familiar? You're not alone. One developer working on an e-commerce recommendation engine discovered that "scikit-learn and pandas libraries increased the size of my deployment package beyond the AWS Lambda package limits." Another found their TensorFlow model loading caused API calls to timeout after 29 seconds. Here…  ( 8 min )

    Your servers are spiking and you need to be able to cope without breaking the bank. Let’s move you to the cloud, where you can deal with your new demand with cost-effective ease. A Virtual Private Cloud (VPC) is essentially your own private network slice within the cloud, fully isolated from other tenants. Inside a VPC, you get to define your IP address ranges, create public and private subnets, and set up route tables and internet or virtual private gateways to control traffic flows. Setting up is important. Instead of hosting your servers in a flat network, it’s best to have a VPC (Virtual Private Cloud).

    Day 1 - Session 2: JavaScript Basics (Datatypes,Variables, Functions & More)
    Hello Devs! ✌️ In today’s session, we’re diving deeper into JavaScript fundamentals. If you’re just getting started, this will help set a solid base. Let’s break it down simply. 📌 Datatypes: JavaScript has different types of data you can work with. The most common are: • String→ text → "Hello World" Number → numbers → 42, 3.14 Boolean → true/false → true, false Undefined→ no value assigned Null → intentionally empty Object → key-value pairs → {name: "Alex"} Array→ list of items → [1, 2, 3] ⮞ Example: let name = "Alex"; // string let age = 25; // number let isStudent = true; // boolean 📌 Variables: We store data in variables. In modern JS, we mostly use: •let → value can change const→ value cannot change (constant) ⮞ Example: let city = "New York"; city = "London"; // this works const country = "USA"; // country = "Canada"; // ❌ error 📌 Functions A function is a reusable block of code that performs a task. ⮞ Example: function greet() { console.log("Hello!"); } We call or invoke a function like this: greet(); // Output: Hello! 📌 Return & Arguments Functions can take arguments (inputs) and return outputs. ⮞ Example: function add(a, b) { return a + b; } let sum = add(5, 3); // sum = 8 console.log(sum); // Output: 8 📌 String Concatenation We combine (concatenate) strings using +. ⮞ Example: let firstName = "Alex"; let lastName = "Smith"; let fullName = firstName + " " + lastName; console.log(fullName); // Output: Alex Smith 🚀Quick Recap ✔ Datatypes help define the kind of data. Variablesstore data. Functions let us organize reusable logic. Arguments & returnallow input and output. Concatenation connects strings. That’s a wrap for Session 2! Thanks for reading — happy coding! ✨  ( 3 min )

    Difference between Java and JavaScript day-1(discuss)
    Java is a statically typed, object-oriented programming language for building platform-independent applications. JavaScript is a dynamically typed scripting language primarily used for interactive web development. Despite similar names, they serve different purposes and have distinct syntax, runtime environments, and use cases. JavaScript was created in the first place for DOM manipulation. Earlier websites were mostly static, after JS was created dynamic Web sites were made. Functions in JS are objects. They may have properties and methods just like other objects. They can be passed as arguments in other functions. Can handle date and time. Performs Form Validation although the forms are created using HTML. No compiler is needed.

    How to Create a Beautiful Public Profile Page for Free Without Facebook or Instagram
    I use Google Maps a lot to find local shops and services — cafés, tattoo artists, yoga studios. But too often, their links lead to Instagram or Facebook pages, where I have to accept cookies, dodge login popups, or scroll past ads just to access basic info like opening hours or a portfolio. It’s frustrating. This kind of information should be public by default — not locked behind Meta’s walls. This Isn’t What the Web Was Meant For. Small businesses deserve better than to have their storefronts locked behind walled gardens. And people deserve access to that info without handing over their data to Meta. They should publish it on a bluesky account instead! I’m working on hopefully.blue — a new tool that gives small businesses a clean, Bluesky-powered profile page. Think Linktree meets Micro.blog, but for Bluesky. Your business posts to Bluesky. We generate a public-facing profile that lives outside Meta/ X (any other big corp). No login needed. No cookies. Just your info, presented beautifully. Your bio and pinned post become your “About” section. Your latest photos show up on the side as an image wall. It's free It’s fast, privacy-friendly, and 100% public. Here are a few examples: spencer 🦈, a Marine Biologist Ahoy Conference Malika Favre 404media Apollonia Saintclair It works with any Bluesky account (You can find mine here ) - all the data is loaded behind the scene (thanks to their amazing API) and hydrates a Sveltekit frontend app. It's available in five languages (using paraglideJS).

    Recreating a Nostalgic Game with Q CLI
    Back when I was studying at the College of Engineering, Trivandrum (Any CETians here?), during my MCA days, we had tons of fun in our hostel rooms. Only one of us had a UPS for his computer, so whenever there was a power cut, we all gathered in his room. His screen was the only one lit up, and we’d play a Flash game called Hangaroo—a Hangman clone where you had to guess the word before the kangaroo met its fate! Those memories still bring a smile to my face. When I came to know about the Q CLI Game Challenge, I immediately knew what I was going to build - a recreation of dear old Hangaroo! Q CLI is a wonderful coding assistant that natively works in your terminal. I was able to build 90% of the functionality with just one prompt. Then I spent a couple of hours tweaking the looks and gamep…  ( 4 min )
    Understanding `TransactionEventListener` in Spring Boot: Use Cases, Real-Time Examples, and Challenges

    The Invisible Workload: What Remote Dev Teams Get Wrong About Burnout
    Burnout doesn’t always look like exhaustion. In today’s remote-first development culture, most teams think they’re “avoiding burnout” just because their people aren’t clocking 80-hour weeks or complaining. But burnout isn’t always loud. Often, it’s silent, cumulative, and invisible—especially in distributed engineering teams. 🔍 What Developers Are Actually Burning Out From 🌀 Context switching 12 times before lunch 📆 Endless meetings that should’ve been comments 😶‍🌫️ Lack of visibility into the team’s real goals ⏳ Deliverables without clarity on “why now?” 🧱 Tech debt and patchwork systems that slow down deep work 🤐 Feeling invisible unless they’re overcommunicating The irony?

    Centralized Logging for Docker: What Are Your Options?
    When you run a lot of Docker containers, it can be hard to see what is going on. Each container writes logs and these logs might be important. They help you know if something is broken. They also help you understand how your app is working. But logs from many containers on many servers? That can get messy. This is why people use centralized logging. Centralized logging means all logs go to one place so that you can look at them easily. In this post, we will talk about how to collect logs from Docker. We will see what tools people use. And we will look at the pros and cons of each. Logs are like notes that your app writes. These notes say what the app is doing. If the app crashes, the logs can tell you why. If users have problems, the logs help you understand them. Without logs, fixing bugs…  ( 5 min )

    Understanding Polygons and `ST_` Functions in PostGIS
    PostGIS is a powerful spatial extension for PostgreSQL that allows you to store, query, and manipulate geographic objects. If you're working with maps, geometry, or location-based data, PostGIS is an essential tool. In this article, we’ll explore what a polygon is in PostGIS, what the parameters in a polygon definition mean, and the role of ST_ functions in spatial queries. A polygon in PostGIS is a two-dimensional geometric object that represents an enclosed area defined by one or more rings: The outer ring defines the exterior boundary. Inner rings (optional) define holes within the polygon. Each ring is made up of at least four coordinate points, and the first and last point must be the same to form a closed loop. Consider the following SQL query: SELECT ST_GeomFromText('POLYGON((0 0, 0…  ( 4 min )

    Australian Army Tests AI to Deceive Enemies via Radio Signals
    The Australian Army is currently trialling an advanced artificial intelligence (AI) system named TrapRadio, designed to generate deceptive radio communications to mislead adversaries and enhance frontline protection. Developed by British-Australian company Penten Amio, TrapRadio employs AI to create synthetic radio traffic that mimics high-value communications or transmission patterns, effectively diverting enemy attention and resources away from actual operations. This technology mirrors cybersecurity strategies where decoy systems and data are used to distract threat actors. TrapRadio was recently tested during a large-scale international military exercise in California, involving 140 Australian Defence Force personnel. The system demonstrated its capability to support soldiers through force protection and by creating dilemmas for adversaries via AI-generated deceptions. Captain Wayne Mulhall from the Electronic Warfare division at Army Headquarters highlighted TrapRadio's potential to reshape the battlefield by mimicking high-value targets, thereby creating strategic dilemmas for enemy operators. This initiative underscores the Australian Defence Force's commitment to integrating cutting-edge AI technologies to enhance operational effectiveness and soldier safety.

    📝 JavaScript Basics: Global & Local Variables, Linking to HTML, and the DOM
    JavaScript is one of the most widely-used programming languages for web development. Whether you're just getting started or brushing up on the basics, understanding how variables work and how to connect your code to HTML is essential. In this post, we’ll explore: What are global and local variables? How to link JavaScript in an HTML file. Before you can run JavaScript, you need to link it to your HTML file. There are two common ways to do this: 1. Inline JavaScript(not recommended for large projects) 2. External JavaScript File (best practice) Create a file named script.js: // script.js Link it in your HTML file: ✅ Tip: Global Variable A global variable is declared outside of any function. It can be accessed and modified anywhere in the code. let globalMessage = "I'm a global variable!"; function showMessage() { Local Variable A local variable is declared inside a function. It can only be accessed within that function. function showLocalMessage() { ⚠️ Remember: The DOM is a programming interface for HTML and XML documents. It represents the page so that programs (like JavaScript) can change the document structure, style, and content. Example: HTML: Hello! JavaScript: function changeText() { } When the button is clicked, the text will change — thanks to JavaScript and the DOM. Topic Key Point Global Variable Declared outside functions; accessible everywhere Local Variable Declared inside functions; limited scope Linking JS Use tag with src or inline DOM Lets JavaScript interact with HTML elements  ( 3 min )
    Saved EBS Costs by Cleaning Up 3 TiB of Duplicate Data in InfluxDB v1
    Hi, I’m rhara, a software engineer at Axelspace. In this post, I’ll share how we reduced the size of an InfluxDB OSS v1 EBS volume from 5.9TiB to 2.9TiB by removing duplicate data. Since I couldn’t find much information on this process, I’m writing this as both a record and a reference. Note: This method requires creating a new InfluxDB database with a different name, meaning the original database name cannot be retained. To restore the original name, additional steps such as using the SELECT * INTO clause again are required. InfluxDB is a time-series database optimized for storing and querying time-based data, especially in use cases where high write and read throughput is important—such as log aggregation. (Docs) At Axelspace, we use InfluxDB to store satellite telemetry data, such as p…  ( 5 min )
    Is This a Refreshing Way to Understand Association?
    The definition of association in SQL is overly simplistic: association is essentially performing a Cartesian product of two tables and then filtering the result, expressed in syntax like A JOIN B ON .... Python’s approach to association largely follows the SQL approach, with similar concepts and methods. However, esProc SPL understands association differently, with a definition that is no longer related to the Cartesian product. SPL divides association into two categories. One is called foreign key association, which refers to the association between a regular field (foreign key) of one table and the primary key of the other. For example, the foreign keys employee_id and customer_id of the orders table are associated with the primary keys of the customers and employees tables, respectively…  ( 8 min )

    📝 JavaScript Basics: Data Types, Variables, and Functions
    __ _1️⃣ Data Types in JavaScript JavaScript has several built-in data types. These are categorized into primitive and non-primitive (object) types. String – Text data let name = "Alice"; Number – Integer or floating-point numbers let age = 25; Boolean – true or false let isStudent = true; Undefined – A variable that has been declared but not assigned a value let x; Null – Represents an intentional absence of value let data = null; Symbol – Unique and immutable primitive value BigInt – For large integers 🔸 Non-Primitive (Objects, Arrays, Functions) let person = { name: "Bob", age: 30 }; *2️⃣ Variables: var, let, and const JavaScript uses keywords to declare variables: var – Function-scoped (older way) let – Block-scoped, can be reassigned const – Block-scoped, cannot be reassigned let city = "New York"; 3️⃣ Functions in JavaScript Functions are reusable blocks of code that perform specific tasks. function greet() { 🧪 Calling a Function greet(); // Output: Hello, world! *4️⃣ Function Arguments You can pass values to functions using arguments. function greetUser(name) { greetUser("Alice"); // Output: Hello, Alice! 5️⃣ Return Values Functions can return values using the return keyword. function add(a, b) { let sum = add(5, 10); ✅ Conclusion JavaScript becomes powerful once you understand its core components: Data types help store different kinds of information Variables let you store and reuse that data Functions allow you to organize and execute logic in a clean way In the next post, we’ll explore control flow with if, else, loops, and more!  ( 3 min )
    Clean Architecture in .NET: Moving Beyond Generic Repositories and Leveraging IServiceScopeFactory
    Abstract Introduction Clean Architecture: Principles and Pragmatism Core Layers: Entities: Domain models containing business rules, isolated from infrastructure concerns The fundamental principle—the Dependency Rule—ensures that business logic remains independent of infrastructure decisions, enhancing testability and maintainability. Complex business domains requiring sophisticated modeling When They Become Overhead: CRUD-centric applications with straightforward business rules The key insight is that architectural patterns should solve actual problems, not theoretical ones.

    🌍🔒 **Local and Global Variables in JavaScript
    📌 1. Global Variables A global variable is declared outside of any function and can be accessed from anywhere in the code (inside or outside functions). Example: let globalVar = "I am global"; function showGlobal() { console.log(globalVar); // Can access globalVar } showGlobal(); console.log(globalVar); // Also accessible here 2. Local Variables A local variable is declared inside a function (or block using let/const) and can only be accessed within that function or block. Example: function showLocal() { let localVar = "I am local"; console.log(localVar); // OK } showLocal(); // console.log(localVar); // ❌ Error: localVar is not defined Block Scope with let and const Variables declared with let or const are block-scoped, which means they're only accessible within { } braces. if (true) { let blockVar = "Inside block"; console.log(blockVar); // OK } // console.log(blockVar); // ❌ Error Note on var var is function-scoped but not block-scoped. function testVar() { if (true) { var x = 10; } console.log(x); // ✅ Works: x is function-scoped } testVar(); Comparison Table Type Scope Accessible From Keyword Global Entire script Anywhere var, let, const (outside) Local Function/Block Only inside its block let, const, var (inside) Global Variable = Accessible anywhere in the file. Local Variable = Accessible only inside the function or block where it’s declared.  ( 3 min )

    Hardening Docker Images for PCI-DSS Compliance: Practical Strategies for Secure Builds
    When working toward PCI-DSS compliance in containerized environments, one of the most critical components to get right is the container image itself. Docker images form the foundation of your deployed applications, and any misconfiguration, vulnerability, or bloat at this level can have cascading effects on your security posture. PCI-DSS emphasizes minimizing the attack surface, enforcing least privilege, and maintaining traceable controls - all of which can (and should) be implemented directly during image creation. Start by choosing your base image carefully. Bloated, outdated images not only increase the size of your containers but also multiply the number of possible vulnerabilities. Use minimal, purpose-built base images like Alpine or Distroless whenever possible. These images contai…  ( 5 min )

    Understanding PCI-DSS in Docker: Laying the Foundation for Secure Containerized Payment Systems
    The Payment Card Industry Data Security Standard (PCI-DSS) outlines stringent security requirements for any system handling credit card data. With the rise of containerization, many developers and DevOps teams are turning to Docker for flexible and scalable deployments - even in environments where PCI compliance is required. However, deploying containers in a PCI-regulated ecosystem demands careful attention to isolation, access control, auditability, and secure configuration. At its core, PCI-DSS mandates strong controls around data encryption, user access, secure software development practices, network segmentation, and continuous monitoring. These goals are fully achievable within containerized environments, but they require an understanding of how Docker behaves and how to configure it…  ( 4 min )

    Handling X -> Y -> X Relationships in Rails
    I'm creating another publishing database, and this time I have to get the relationships between publishers correct. Up until now, I've been able to cheat a bit as the publishers that I work with tend to be in the film and TV music business and have pretty simple publishing needs. But it's time to really model this properly. Publishers can make deals with other publishers. There are two deals that we're specifically interested in: Subpublishing Administration There's no need to get too far into the specifics of these deals, but in general one publisher is the "assignor" and the other is the "assignee" (or "acquiror").

    Harmonyos Cangjie Language Development Tutorial: The Lifecycle of Pages and Components
    Good morning, everyone. Today's topic is about the life cycle in Cangjie's language development. In fact, You LAN Jun prefers to share practical code writing and doesn't like to talk too much about theoretical things. The reason why I wrote a separate article today to share the content of the life cycle is that if this part is not covered, it's really easy to fall into a trap. The life cycle refers to the process from loading, displaying to disappearing of a page or component. During this process, there will be some system events, and we can perform some operations in it. For instance, in ArkTs, there are methods such as aboutToAppear() and onPageShow(). So, what is the life cycle like in Cangjie? If you have no knowledge of Cangjie and can only try to write it in the ArkTs way, you will f…  ( 3 min )

    Document Everything!
    This is one of the most powerful habits I wish remote teams adopted more. Documenting everything. Not because you love writing things down for the sake of it. But because clear, accessible documentation is what makes async work. When decisions live in your head (or in some Slack Channel), people have to ask to catch up. Which means more meetings. More repeating. More “Can you remind me where that stands?” More/Better documentation means… → Everyone has the context they need Async doesn’t mean you lose visibility. It means you gain clarity—without the meeting. Because if your documentation does the talking, your team can get back to building.  ( 3 min )

    EKS Cost Optimization Guide: Best Practices and Tips for 2025
    Amazon EKS (Elastic Kubernetes Service) makes running Kubernetes on AWS easier, but keeping costs under control can be a challenge. As your workloads grow, so do the expenses, and without a clear strategy, it’s easy to end up with a sky-high cloud bill. According to the 2025 State of Cloud Costs by Datadog, over 80% of container spend goes to waste. Most teams over-provision CPU and memory to handle peak loads, but actual usage rarely matches these allocations. This leads to underutilized nodes, inflated infrastructure costs, and inefficient autoscaling. To optimize EKS costs effectively, you need to understand where your money is going and how to make the most of your resources. In this guide, we’ll break down the key areas of EKS cost management and share practical tips to help you reduc…  ( 10 min )

    Solana chart hints at 180% rally to $300 if key technical trend holds
    Key takeaways: Historical chart patterns and the Fibonacci Retracement metric hint at a Solana price rally to $300. Solana’s $7.5 billion in futures open interest and negative funding rates could be a sign that a powerful short squeeze is in the making. Solana (SOL) price tested the $180 resistance level on May 11, but it has since consolidated below this key threshold and appears unable to establish a sustained bullish position. However, the altcoin has maintained a positive signal by closing above the 50-week exponential moving average (EMA) for three consecutive weeks. This critical level has historically acted as a catalyst for significant price rallies. Solana 1-week chart.

    Ethereum bulls aim for $2.7K ahead of ETH’s $2.4B options expiry
    Key takeaways: 97% of ETH put options will expire worthless if ETH holds above $2,600. A bullish ETH price outcome could be limited by macroeconomic factors and trading strategies that cap Ether gains. On May 30, $2.4 billion in Ether (ETH) options will expire—an event that could support ETH’s attempt to break above the $2,700 mark for the first time in over three months. Despite the recent gains, Ether is down 21% in 2025, while the broader cryptocurrency market has seen a 5% increase. Ether bulls are motivated to keep ETH above $2,600 ahead of the monthly expiry. However, weak network activity on Ethereum suggests that the upside potential may be limited. Ether/USD (blue) vs. Total crypto capitalization (green).

    Labor Department rescinds Biden-era guidance for crypto in 401(k) plans
    The US Labor Department has officially rescinded guidance issued during the Biden administration that limited the inclusion of cryptocurrency in 401(k) retirement plans. On May 28, the Labor Department revoked a 2022 guidance that had urged fiduciaries to be “extremely cautious” when considering cryptocurrency for 401(k) retirement plans. The move could give asset managers more flexibility to include digital assets in retirement investment options. The government agency removed the guidance asserting that it represented a departure from the department’s “historically neutral, principled-based approach to fiduciary investment decisions.” “We’re rolling back this overreach and making it clear that investment decisions should be made by fiduciaries, not D.C. bureaucrats,” said US Secretary of…
    Bitcoin analyst says BTC price peak in $220K to $330K range still possible
    Key takeaways: Bitcoin researcher Sminston With says BTC could gain 100% to 200%, with a cycle peak between $220,000 to $330,000. Bitcoin continues to exhibit strong cyclical volatility, contradicting the belief that its price swings are softening over time. Over $4 billion in BTC has been moved by long-term holders, warning of a price correction. Analysis from Bitcoin (BTC) researcher Sminston With implied that a BTC price peak is still 100% to 200% away from current prices. In a recent X post, With shared a Bitcoin price chart using a 365-day simple moving average (SMA) aligned with a power law model (R²=0.96). The model suggests Bitcoin’s price follows a predictable, non-random pattern over time, distinct from the exponential growth models often applied to stocks and equities. Bitc…
    Pakistan announces Bitcoin strategic reserve
    Bilal Bin Saqib, head of Pakistan’s crypto council, announced on May 28 that the country is moving to establish a strategic Bitcoin reserve. Speaking at the Bitcoin 2025 conference in Las Vegas, Nevada, Saqib said the government of Pakistan followed the United States’ lead in establishing a Bitcoin strategic reserve and is embracing pro-crypto regulatory policies. The government official told the audience: "Today is a very historic day. Today, I announce the Pakistani government is setting up its own government-led Bitcoin Strategic Reserve, and we want to thank the United States of America again because we were inspired by them." The announcement represents a significant departure from the government of Pakistan’s previous stance on cryptocurrencies, holding that crypto would never be legal in the country. Pakistan’s shift reflects the broader trend of nation-states adopting pro-crypto policies following the regulatory shift in Washington, DC under the President Donald Trump administration.

    Bitcoin’s physical infrastructure is the industry’s most overlooked asset
    Opinion by: Scott Buchanan, chief operating officer of Bitcoin Depot A new proposal to install Bitcoin ATMs in federal buildings highlights an important question: Can crypto truly go mainstream without a stronger physical presence? For years, the industry has focused on software and decentralization, but its reluctance to invest in real-world infrastructure is starting to show. Without physical access points, crypto risks becoming an exclusive, insiders-only system, rather than the open alternative it sets out to be. Everyone loves to talk about decentralization. There’s a good reason behind this. It defines the movement, shapes the technology, and supports the vision of a better financial system. While the industry focuses on code and algorithms, it lacks something basic. A decentralized …

    Why is Bitcoin price stuck?
    Key points: Bitcoin price is stuck in a range, with overhead resistance at $110,000 continuing to obstruct a rally to new all-time highs. Traders are in a wait-and-see mood due to uncertainty surrounding macroeconomic events. Bitcoin’s (BTC) bull run has stalled, with the price consolidating within a roughly $3,500 range since May 23. The $110,000 level proves to be a stubborn barrier. BTC/USD four-hour chart. Cointelegraph/TradingView Let’s look at some of the reasons why Bitcoin price remains stuck. Bitcoin runs into resistance at $110,000 Data from Cointelegraph Markets Pro and Bitstamp shows that BTC price oscillates within a tight range between $106,600 and $110,700, with no clear directional bias.

    Amina Bank hits $40M revenue in 2024 as crypto AUM doubles
    Swiss crypto bank Amina Bank, formerly Seba Bank, reported record financial results for 2024, with revenue climbing 69% year-over-year to $40.4 million. The bank also saw its assets under management (AUM) rise by 136% to $4.2 billion, driven by institutional demand and strategic expansion, according to a May 28 news release. The Zurich-based bank credited the growth to its multi-jurisdictional footprint, 24/7 trading capabilities and a lending book that has maintained zero defaults over five years. “I’m incredibly proud of our team’s tenacity and focus, which led to quarterly profitability in Q4 2024, a pivotal milestone that confirms the value of our approach,” CEO Franz Bergmueller said.

    BlackRock to join Telegram’s $1.5B bond sale: WSJ
    BlackRock, one of the world’s largest Bitcoin holders, is reportedly participating in a bond raise by crypto-friendly messenger Telegram. Telegram is expected to raise at least $1.5 billion in a bond issue on May 28, with support from existing backers like BlackRock and Abu Dhabi’s investment firm Mubadala, The Wall Street Journal reported. As part of the sale, Telegram is offering investors five-year bonds at a 9% yield, the report said, citing sources familiar with the matter. Telegram plans to use the proceeds to buy back remaining debt from bonds issued in 2021, which are due to mature in March 2026. Discounts for potential Telegram IPO Apart from existing Telegram bondholders like BlackRock and Mubadala, the sale is also expected to bring new investors, including the US hedge fund firm Citadel. The WSJ report came weeks after Bloomberg first reported on Telegram's bond sale in late April, with sources claiming that the company was holding investor meetings about a bond sale worth about $2 billion to refinance its debut debt offering from 2021. According to the Financial Times, Telegram’s new bond offering will allow investors to buy shares in a potential initial public offering at a 20% discount, mirroring the terms of previous bond sales. This is a developing story; further information will be added as it becomes available. Magazine: Bitcoin bears eye $69K, CZ denies WLF ‘fixer’ rumors: Hodler’s Digest, May 18 – 24
    Fungible cryptos in secondary sales are not securities, Ripple tells SEC
    Ripple, the blockchain company behind XRP, argued that fungible cryptocurrencies are not securities when transferred in secondary transactions in a recent letter sent to the US Securities and Exchange Commission (SEC). In its May 27 letter, Ripple cited US attorney and crypto law thought leader Lewis Cohen to support its claim. In his widely cited 2022 paper, “The Ineluctable Modality of Securities Law: Why Fungible Crypto Assets Are Not Securities,” he wrote: “[T]here is no current basis in the law relating to ‘investment contracts’ to classify most fungible crypto assets as ‘securities’ when transferred in secondary transactions.” In his paper, Cohen explained that in secondary transactions, an investment contract transaction is generally not present. He further claimed that fungible cry…

    Sui validators vote on $162M Cetus recovery plan to restore user funds
    Sui-based decentralized exchange Cetus may be one step closer to recovering funds lost in a recent exploit, pending the outcome of a community governance vote scheduled to end June 3. Cetus was exploited for over $220 million worth of digital assets on May 22. Shortly after the incident, Cetus managed to freeze $162 million of the funds. In a May 27 post on X, Sui said Cetus had requested a community vote to approve the recovery of the frozen funds. “If the community vote is approved, the funds will be recovered from the attacker and held in a multisig trust account until they can be returned to accounts that had positions in Cetus,” the post said. The vote is part of a broader recovery plan that includes using Cetus’s treasury and securing an emergency loan from the Sui Foundation. Sou…

    Crypto czar Sacks says US could possibly ‘acquire more Bitcoin’
    White House AI and crypto czar David Sacks says the US could buy more Bitcoin if the government can fund the purchase in a “budget-neutral” way without a tax or adding to the growing national debt. Sacks told Gemini co-founders Cameron and Tyler Winklevoss during a May 27 fireside chat at the Bitcoin 2025 conference that while he “can’t promise anything,” a pathway does exist for the government to buy more Bitcoin (BTC). However, it would require convincing Commerce Secretary Howard Lutnick or Treasury Secretary Scott Besson to OK the buy and fund it “without a new tax or adding to the debt,” Sacks said, adding that “maybe by finding the money from some other program that’s not using it — then we could potentially acquire more Bitcoin.” David Sacks said the US could buy more Bitcoin, but h…
    Australian regulator takes former Blockchain Global director to court

ASIC alleged Guo made multiple breaches of directors’ duties relating to his dealings with ACX Exchange customer funds, and claimed he made false and misleading statements about those dealings and failed to maintain proper books and records.  The now-liquidated Blockchain Global operated the ACX Exchange from mid-2016 until December 2019, when it collapsed as customers could no longer withdraw their assets.  During liquidator’s examinations in 2022, the courts were told that ACX exchan…
    Altcoin ‘wildfire’ inbound as trader shuts down bear market fears

    IMF says El Salvador to make ‘efforts’ to stop Bitcoin buys with $120M payments deal
    The International Monetary Fund said it has reached an agreement with El Salvador to pay the country $120 million following an initial review of its $1.4 billion loan agreement struck last year. The IMF said on May 27 that as part of the deal, El Salvador will need to fulfill its prior obligations around limiting further government involvement in Bitcoin (BTC), and it will have to cease its involvement in the Chivo wallet by the end of July. “On Bitcoin, efforts will continue to ensure that the total amount of Bitcoin held across all government-owned wallets remains unchanged,” the global lender said. The planned payout, subject to IMF executive board approval, is part of a larger $1.4 billion, 40-month loan deal struck in December, which saw El Salvador agree to confine its Bitcoin ambiti…
    CFTC’s Goldsmith Romero says commissioner exodus ‘not a great situation’
    Outgoing US Commodity Futures Trading Commission commissioner Christy Goldsmith Romero says the exodus of the agency’s top brass is “not a great situation” for crypto regulations. The CFTC could be headed by just one commissioner once the other four depart later this year, which Goldsmith Romero said in a May 27 interview at the Brookings Institution will make creating regulations harder because it leaves a less diverse pool of opinions.  “I think it’s not a great situation if you have one person who’s determining what the rules should be; you lose the benefit of this back-and-forth, this push-and-pull as to what’s the right thing to do,” she said. “I’ve always wanted to hear from my fellow commissioners about what makes sense to them, and there are many things that they’ve convinced me of…
    Trump’s CFTC pick Quintenz discloses crypto links, $3.4M assets

In paperwork released by the US Office of Government Ethics on May 25, Brian Quintenz disclosed his key positions in crypto and market firms that would directly relate to the CFTC’s regulatory priorities and disclosed assets worth at least $3.4 million, according to a May 27 Bloomberg report.  Quintenz was a CFTC commissioner from 2017 to 2021 and is currently the global head of crypto policy at Andreessen Horowitz, a position he said he will step down from if the Senate confirms him as CFTC chair.  He holds an interest in three AH Capital Management investment funds, CNK Fund III, CNK Seed 1 Fund,…
    Rep. Steil urges restraint on adding ‘non-germane items’ to crypto bills
    US Representative Bryan Steil wants lawmakers to stop adding “non-germane items” into two key crypto bills, claiming that doing so is slowing the implementation of a regulatory framework for the industry. “Individuals, when they see legislation that’s going to move forward, want to attach non-germane items to any bill that’s going to move through and be signed into law,” Steil, a Republican from Wisconsin who chairs the House Financial Services Subcommittee on crypto, told Cointelegraph at the Bitcoin 2025 conference in Las Vegas on May 27. “We have to restrain ourselves from that instinct and attempt by our colleagues — both sides of the aisle,” he added.

    Jack Dorsey’s Block to bring Bitcoin payments to Square by 2026

The company announced the plan at the Bitcoin 2025 conference in Las Vegas on May 27, where Block demonstrated the feature at the BTC Inc. merchandise store. Merchants will be able to accept Bitcoin (BTC) payments through existing Square hardware using the Lightning Network, Bitcoin’s faster, lower-cost layer-2 scaling network.  “Merchants can choose to hold the Bitcoin, or auto-convert it to fiat in real-time,” Dorsey said on X.  The company said it expects to start rolling out in the second half of 2025, reaching all eligible Square sellers by 2026, subject to regulatory approvals.  The move builds on …
    Bitcoin’s ‘aggressive leg higher’ in Q3 still up in the air: Analyst
    Bitcoin’s recent all-time high of $111,970 has sparked optimism among crypto market participants, but whether that carries through into the third quarter of this year remains uncertain, analysts say. “The coming weeks will likely determine whether Bitcoinʼs latest breakout was a local high or the prelude to a more aggressive leg higher in Q3,” Bitfinex analysts said in a May 28 markets note. Consolidation or mild retracement may “be healthy” Bitcoin (BTC) reached new all-time highs of $111,970 on May 22, however, Bitfinex analysts say a continued price increase alone won’t necessarily confirm the uptrend heading into the next quarter.  “A period of consolidation or mild retracement would not only be healthy but also provide a more sustainable foundation for the next leg higher,” the analys…
    Real-world assets could revitalize dying NFT lending market: DappRadar
    Real-world assets linking up with non-fungible tokens (NFTs) is one of a few key catalysts that could reignite the waning NFT lending sector, which is suffering from a collapse in volumes and user activity, says blockchain analytics platform DappRadar. Volumes in the NFT lending market, which allows NFT holders to take out a loan against their token, have dropped 97% from a peak of around $1 billion in January 2024 to $50 million in May, DappRadar analyst Sara Gherghelas said in a May 27 report. Gherghelas said for NFT lending to “move beyond survival mode,” it needs “new catalysts” to reignite the sector, such as real-world asset NFTs, like tokenized real estate or yield-bearing assets that could unlock more stable, trusted collateral sources. “So far, 2025 has not delivered a compelling …

Yet, beneath the innovation lies a shadow of risk—adversaries empowered by those same sophisticated tools. With criminal capabilities intensifying, financial institutions must navigate an increasingly nuanced battleground. To safeguard trust in an era defined by relentless technological evolution, finance faces a balancing act: leveraging AI's limitless potential while fortifying against its darker uses.

    Sell Yourself as a Developer: Creating a Personal Brand That Stands Out
    In a world full of portfolios, GitHub profiles, and online résumés, it’s easy to feel like one developer in a sea of sameness. But here’s the truth: if you want better opportunities, better projects, and more control over your career—you need to sell yourself. And that starts with a personal brand. You might think “branding” is just for influencers and startups. Not true. As a developer, your brand is your reputation made visible. Here’s how to build it, own it, and let it open doors. ⸻ 🧭 Know What You Want to Be Known For Before you can create a personal brand, you need clarity.

    Artificial General Intelligence: 6 Definitions, 6 Perspectives, 6 Predictions
    Artificial Intelligence (AI) is everywhere, but Artificial General Intelligence (AGI) is something entirely different. While AI powers chatbots, image generators, and recommendation engines, it remains narrow—trained for specific tasks. AGI, by contrast, refers to a still-hypothetical system capable of understanding and performing any intellectual task a human can. Yet despite growing attention, AGI has no single agreed-upon definition. What exactly qualifies as “general” intelligence? And how close are we to achieving it? Below are some influential quotes that attempt to define what AGI really means. 6 Definitions “AGI is a highly autonomous system that outperforms humans at most economically valuable work.” OpenAI Charter, 2018 “AGI would be a system that is able to perform human-level…  ( 4 min )

    An LLM Evaluation Framework for AI Systems Performance
    One of the challenges of AI systems development is ensuring that your system performs well not just when it is initially released, but as it grows and is deployed to the world. While AI prototyping projects are fun and exciting, eventually systems need to make it to the real-world and evolve over time. These evolutions can come in the following forms: Changing the system prompt to try to improve performance or resolve issues Adding new tools for AI systems to call in function-calling scenarios. This is particularly relevant when working with tooling like Semantic Kernel or Model Context Protocol (MCP) Changing the data that is accessible to models for Retrieval Augmentation Generation. This often comes naturally over time as new data is added. Regardless of the cause of change, organizati…  ( 10 min )
    Decoding"Attention Is All You Need......."

Its an influential work in deep learning and NLP that introduced the Transformer architecture, now the foundation for models like GPT, BERT, and T5. (T in all these names stands for transformer.) This paper basically created modern AI as we know. Every major model as of 2025 is built off this idea. Without this paper, your AI memes, GPT side projects, AI-generated rap battles and that billion dollor GenAI startup idea wouldn't exist. So if you get this paper, you get modern AI.

    Today’s Progress – Odin Project Foundation Course
    Started learning The Odin Project's foundation course — everything was going smoothly until I reached the installation chapter. That part alone took me the whole day 🤦‍♀️ In total, from starting the course to finally getting through the installation chapter, it took me 8 hours. 😩 I had so many questions and got super confused during the installation process. I kept googling things, checking images, and asking ChatGPT — and slowly it started to make more sense. (Not gonna lie, Google Images helped more than anything else 😂). Initially, I tried installing **Ubuntu **through PowerShell, but it didn’t go well. Then I tried installing it from the Microsoft Store, but that version wasn’t working either. Strangely, the "incomplete" installation from PowerShell started working out of nowhere. Not sure what really happened, but it seems to be working fine now. 👍 I haven’t moved on from the chapter yet — just making sure Ubuntu is installed correctly and running well. I asked ChatGPT how to check that, and so far, all the tests are coming back fine. I’ve always wanted to try Linux, but I had this fear that my old and slow PC might crash or something. Now, I feel like I’m slowly convincing myself to properly learn and use Linux. ✌ "There is only one thing more painful than learning from experience and that is not learning from experience."

    Step-by-Step: Generate SSH Key Pair for CI/CD
    To use SSH for CI/CD in GitHub Actions, you need to generate an SSH key pair and add: The private key to your GitHub repo secrets. The public key to your server’s authorized keys. Here’s how to do it: Run this in your terminal (Linux/macOS/git bash/WSL): ssh-keygen -t ed25519 -C "github-deploy" If your system doesn’t support ed25519, you can use: ssh-keygen -t rsa -b 4096 -C "github-deploy" When prompted: Enter file name: You can name it something like ~/.ssh/github_cicd Passphrase: Leave empty (press Enter) for automation ssh-copy-id -i ~/.ssh/github_cicd.pub deployuser@your.server.ip Replace deployuser with the actual username on your server and your.server.ip with your server IP or domain. If ssh-copy-id isn't available, do this manually: cat ~/.ssh/github_cicd.pub Copy the output and add it to: ~/.ssh/authorized_keys on your server. Open your private key: cat ~/.ssh/github_cicd Copy the entire content (including -----BEGIN OPENSSH PRIVATE KEY----- and -----END OPENSSH PRIVATE KEY-----). Go to your GitHub repository → Settings → Secrets and variables → Actions → New repository secret. Name: SSH_PRIVATE_KEY (paste the private key) ✅ 4. Use the Key in GitHub Actions Your GitHub Actions file is already using this with: - name: Set up SSH uses: webfactory/ssh-agent@v0.7.0 with: ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }} That’s it — GitHub will now be able to SSH into your server during deployment.  ( 3 min )

Normalises units/currency and stores records in MongoDB. Calculates daily deltas and 7‑day averages. Sends the sender an automated market‑trend report. Publishes an open JSON API and a React dashboard so anyone can view live prices. The flow works from any basic e‑mail client, so even users on feature phones with intermittent data can contribute and benefit. Live URL: https://marketmail.vercel.app Test: e‑mail the sample below to send@marketmail.canktech.com.

    Introducing dearme.email
    This is a submission for the Postmark Challenge: Inbox Innovators. I made https://dearme.email/. It's a service that let's you send an email to yourself, which you receive after 30 days. What could you use this for? You can send yourself reminders, check in on your goals, and maybe benefit from the perspective of listening to your past self. In an age where bots are everywhere, it's nice to be able to have a human connection with yourself. Not to mention the fact that you can actually do a bit of time travelling, which is awesome. You can send an email to hello@dearme.email and it will be sent back to you in 30 days. We encrypt the email on our end, decrypt it when it's time to send it back and then we delete the message from our systems. We do demand that you varify your email. If you don't do that within 30 days we delete the message. It's a fairly basic Python/postgres setup with Flask. Postmark really takes care of most of the hard bits here. There's a webhook and a cronjob too, but nothing too fancy. I might add payments later to help cover the postgres costs, which I'll probably build with lemonsqueezy. But assuming there's not a huge demand for this app overnight I should be fine. Postmark has reasonable pricing and they also do some spam detection (which is a concern of mine given that anyone can email). @koaning  ( 3 min )
    Managing AWS EC2 Instances Securely and Easily Using SSH and PuTTY on Windows PC
    As I learn more about cloud computing and AWS, I came across EC2 (Elastic Compute Cloud) – a service that enables me run virtual servers in the cloud. These instances gave me full control over how to set them up and access them. To connect to an EC2 instance securely, I used SSH (Secure Shell). Since I’m on a Windows machine I used a free tool called PuTTY, which helps me manage my instances both safely and conveniently. SSH (Secure Shell) is a secure way to connect to a remote device like a server. Instead of typing in a password I used a key pair – a public key stored on the server and a private key saved safely on my computer. To connect to AWS instance I followed below steps using PuTTY on Windows. What I Used: A running EC2 instance on AWS A .ppt key pair that I downloaded when launching the instance PuTTY installed on my PC. I opened PuTTY. In the Host Name field, I entered the public IP of my EC2 instance (from the AWS console). Under Connection → SSH → Auth, I browsed and selected my .ppk file. I clicked Open to start the session. When prompted for a username, I used ec2-user for Amazon Linux PuTTY is lightweight and easy to use. It helps me: Save sessions for quick connections Use terminal commands like I would on a Linux server Learning how to connect to AWS EC2 instances using SSH and PuTTY has been a valuable experience. It helped me understand the basics of secure server management and gives me hands-on practice in cloud computing.  ( 3 min )

    Design Fundamentals for Developers - 5 Tips that Help You Pretend You Know What You're Doing
    I am not a designer myself, but for the better part of the last decade, I've been involved in a lot of frontend projects and worked closely with design. Having picked up some design fundamentals really helped me in my career and I want to share some of that with you now. TLDR: A designers brain is wired differently, and as a logical thinker you will never be able to comprehend their deep state of being. As a developer, it's not necessary to adapt this state. After all - designers and developers are completely different roles. But it sure helps if you know at least some basics.

    Breaking Down tilegen: A Deep Dive into Image Tiling
    Ever zoomed in on a map and wondered how the experience is so smooth and snappy? That's thanks to tiled image rendering. I recently built a tool called tilegen, which is essentially a tile generator that slices up a high-res image into thousands of tiles across multiple zoom levels, just like Google Maps does (well, almost). This post is a deep dive into what tilegen is, how it works, the quirks I ran into, and how mapping giants like Google do it too. At its core, tilegen takes a massive image (like a satellite photo, map scan, game world, or giant illustration), and cuts it into 256×256 PNG tiles across zoom levels. These tiles can then be loaded on demand by a viewer, allowing users to pan and zoom without downloading gigabytes of image data up front. 🧵 Multi-threaded tile generation u…  ( 5 min )

    Okay, our puppet show is a hit! In our last episode, we saw how the Frontend dazzles the audience, and the Backend(the puppeteers) makes everything happen flawlessly. But who handles all the other behind-the-scenes magic that isn't the puppet or the puppeteer? Who builds the actual theater and makes sure it's safe and sound? How do we add new puppets or change scenes quickly and without mistakes every night? Who watches to make sure the lights don't go out or a rope doesn't snap? What if our show gets so popular we need to open more theaters fast? That, my friend, is the world of DevOps! 🛠️ Think of DevOps as the super-skilled, highly organized stage crew and technical directors for our puppet show. They're not usually designing the puppets (that's Frontend) or pulling the strings…  ( 6 min )

    Guarding the Restricted Section: A Magical Approach to Secure RAG With MongoDB, Permit.io, and LangChain
    This tutorial was written by Han Heloir. At Hogwarts School of Witchcraft and Wizardry, the library is a vast repository of magical knowledge. Among its countless shelves lies the Restricted Section, a place where only students with special permissions may tread. Imagine if every student, no matter their year, house, or purpose, could access any scroll, spell, or prophecy. Chaos would ensue. As AI assistants become more capable, we are in a similar situation. Retrieval-augmented generation (RAG) systems let us ask questions and get context-aware answers powered by our internal documents. But without proper safeguards, these systems can expose sensitive data to unauthorized users. This is the tale of how we built a secure RAG system—one that guards access as vigilantly as Madam Pince—with t…  ( 7 min )

    Structured Story Points: Estimating Engineering Work with Clarity
    Editor’s note: This article was originally submitted to InfoQ. It is shared here in its draft form to open up the conversation and gather feedback from the developer community. Before you can improve delivery, you have to trust your estimates. I didn’t set out to create a new estimation system, but during planning sessions I started noticing a pattern. When engineers debated whether a story was a “3” or a “5,” the number rarely mattered, but the context behind the conversation revealed everything. I kept hearing things like: “This isn’t that much code, but it touches three different systems.” “We don’t even know if that API does what we need yet.” “I can knock this out fast, but I’ll need Jack to unblock me.” “Feels simple, but every time we touch that part of the code, something breaks.” …  ( 8 min )

    Building a Business, Breaking Down: My E-Commerce Experiment
    It all started with a simple idea—selling remote control toys and electronics online. I was excited about it, so I started the process of applying for Stripe business to handle payments. I filled out all the details, and after 51 days of waiting, I got a rejection. I didn’t have time to reapply, so I figured, "Alright, time to find another way." That’s when I came across Meesho, which allows you to resell products for a higher price. The idea clicked, but there was a catch—I needed an e-commerce website to make it work. I decided to take matters into my own hands and build the website. I used Flask for the backend and MongoDB for the database. But then came the tricky part: How do I make sure my customers are legit? To solve that, I used OAuth to let people sign in with Google. This way, I…  ( 5 min )
    How to Add Filters to Repeating Groups or Tables in Bubble.io
    If you're building with Bubble.io and want to make your app more dynamic and user-friendly, adding filters to repeating groups or tables is a must-have feature. In this tutorial, I walk you through how to set up filters using input fields, dropdowns, and more — all without writing a single line of code. 📺 Watch the full tutorial on YouTube: 🔍 Why Filters Matter Repeating groups are powerful, but without filtering, they can become overwhelming for your users. By allowing users to narrow down what they see based on specific criteria, you improve both usability and performance. Use cases include: Marketplaces (filter by category, price, etc.) Dashboards (filter by date, status, owner) CRMs (filter by name, stage, priority) In this tutorial, I cover: Setting up a basic repeating group Adding filters with input fields and dropdowns Chaining multiple filter conditions Best practices for responsiveness and performance Real-world example: filtering a product or transaction list Always double-check your search constraints inside the repeating group’s data source. Use "Ignore empty constraints" to make filters optional. Combine multiple inputs using "Do a Search for" + Advanced filters when needed.

    Vamos falar sobre memory leak (Vazamento de ram)
    Mas, que é o memory leak? Imagina que você tá jogando Mario Kart e eu estou te amassando (com toda a humildade). Cada vez que um personagem usa um item (tipo casco vermelho, banana, cogumelo), o jogo precisa de um espacinho na "memória" pra fazer esse item funcionar. Agora pensa assim: O memory leak é tipo se o Mario jogasse um casco vermelho... e o casco nunca sumisse da pista. Ele bate, acerta, faz o que tem que fazer, mas continua lá, invisível, ocupando espaço. E aí o Luigi joga uma banana, o Yoshi usa turbo, e esses itens também nunca desaparecem de verdade. Com o tempo, a pista vai ficando cheia de itens “fantasmas” que ninguém vê mais, mas que tão ali ocupando espaço e deixando o jogo mais lento ou até travando.

    6 CSS animation libraries to bring your project to life in 2025
    Written by Murat Yüksel✏️ In the old days, CSS animations were handled by a handful of magicians and tricksters, often referred to as CSS Wizard_s_. These wizards knew the ways of CSS and how to make elements go up and down, disappear, fly out, glow, jump, and hide. Their tale was spoken in all known realms, and their arcane magic was feared by many – and sought after by even more. As their fame grew, so did the number of apprentices – people who also wanted to use those arcane spells that made a page transition so smoothly, or gave pleasing loader screens. But the magic was difficult, it took time to master, and when it went bad, it went bad – apps crashed, pages jumped into each other, users couldn’t figure out what was what, and why it was so.

    Natural Processing Language
    When you think about artificial intelligence, the first thing that probably comes to mind is The Terminator—a living robot that can do everything a human can, but faster, better, and smarter. I’m not going to dive into the medieval history of how we went from punch cards to talking computers or how we can now access the entire world from a tiny screen. Instead, I want to focus on one simple idea. Let’s say you want a sandwich. You tell your mom, “Make me a sandwich,” and—without asking how—she makes it. Why? Because she already knows what a sandwich is, how to make it, and what you mean. Now imagine telling a computer the same thing. Unlike your mom, it doesn’t inherently know what a sandwich is, what ingredients are involved, or even what “make” means—unless you give it very specific, structured instructions. That’s what programming is: telling a machine what to do, step by step, in a language it understands. But here’s the twist: What if you didn’t need to be a programmer? What if the computer could understand you just like your mom does? That’s where Natural Language Processing (NLP) comes in. It’s the part of AI that enables machines to understand and process human language. It allows even a “non-techie” to talk to machines and get meaningful responses—whether that’s asking Siri for the weather or using ChatGPT to write a blog post. So yes, you can think of the Terminator again—a robot that walks, talks, and understands commands. But if it doesn’t understand your language, you’d have to explain everything in code, which could take ages (maybe even centuries). The fact that we’ve come this far didn’t happen overnight—it took decades of research and innovation. So here I am, starting my** Natural Language Processing** series. Now it’s your turn: What’s your perspective on AI? How do you see the future of machines that can understand us? Drop your thoughts below!  ( 3 min )

    Send emails with Common Lisp (SMTP, Gmail, Sendgrid, Mailgun…)
    Today I want to give an usage example of cl-smtp. It's a good, maintained library, with a good README but no proper documentation, nor a ready-to-copy-paste usage example. Here it is: (cl-smtp:send-email "mail.server.org" "from@mail.org" "to@mailz.org" "subject" "just a test message from Emacs/Slime." :port 587 :ssl :starttls :authentication (list "from@mail.org" "password")) ;; => ("2.0.0 Bye") The lambda list is: (cl-smtp:send-email host from to subject message :ssl ssl :port port :cc cc :bcc bcc :reply-to reply-to :extra-headers extra-headers :html-message html-message :display-name display-name :authentication authentication :attachments attachments :buffer-size buffer-size :envelope-sender envelope-sender :external-format external-format :local-hostname local-hostname :message-id message-id) This code snippet allows to send an email from Common Lisp with an existing email account: be it Gmail or any other regular email provider, as long as you know its SMTP address or IP, and your account ID and password. Eudoxia's postmaster is a wrapper around cl-smtp and mel-base. It adds object-orientation to create and use servers as first-class objects, as well as some defaults. It uses cl-smtp to send emails, and mel-base to manage pop3/IMAP folders. The repository is now read-only, let's maintain it together on https://github.com/lisp-maintainers/ if you are so inclined. If you want to rely on a third-party email provider, you can create an account there and these libraries have you covered: sendgrid - send emails with Sendgrid's API. mailgun - A thin wrapper to post HTML emails through mailgun.com. trivial-imap wants to make mel-base or post-office (a fork of Franz's cl-imap) easier to use. I didn't try any of them. It even has the possibility to search for emails. Sending (and possibility reading) emails in Common Lisp isn't trendy but just works© ;) for any news please check the list of https://github.com/CodyReichert/awesome-cl/  ( 3 min )

    AI in AdOps: The Future of Yield Optimization and Ad Revenue Management
    The world of digital advertising is undergoing a transformation — and at the center of it is AI-powered AdOps. In 2025, the complexity of programmatic ecosystems is too vast for human-only operations. SSP behavior, bidder variability, session-level segmentation, and privacy-safe targeting require smarter, faster, and more adaptive systems. So where does AI come in? Right at the core of yield optimization, ad revenue growth, and real-time decisioning. 🔄** Dynamic Yield Optimization with AI** Analyze millions of impressions across geos, devices, and session patterns. Predict bid density based on content type and user engagement. Auto-adjust floor prices based on real-time demand elasticity. Instead of relying on quarterly AdOps reviews, publishers can implement models that optimize every single impression. That's not just efficiency, it's precision monetization. 📉 Cutting Through SSP Clutter Redundant SSPs contributing little to incremental ad revenue. Latency culprits reducing auction participation. Auction duplication across sources. The result? A cleaner, faster stack — tuned for performance, not volume. 📊 Log-Level Data + AI = A New Era for AdOps Forecast fill rates. Spot patterns in unfilled impressions. Surface high-revenue paths based on user intent or session context. What used to take weeks of manual log analysis is now being fed into ML models that drive smarter AdOps workflows.  ( 3 min )

    📝 My JavaScript Learning Journey – Day 1 Today, I started learning JavaScript, one of the most important languages for web development. In this blog, I will share what I learned today with simple explanations. JavaScript is used to make websites interactive and dynamic. HTML gives structure, CSS gives style, but JavaScript adds life to the website. Showing alert messages Creating sliders or animations Validating forms (like checking if email is correct) Building real-time updates without refreshing the page A function is a block of code that performs a specific task. to avoid repeating code. Instead of writing the same code again and again, we write it once in a function and call it wherever needed. Example: function greet() { console.log("Hello, welcome to my blog!"); } This function will print a welcome message. how to call this function. To run (or call) a function, just write the function name followed by parentheses (). Example: greet(); // This will print: Hello, welcome to my blog! So, whenever you write greet();, it runs the code inside the function. Variables are containers for storing data. var (older) let (modern and recommended) const (for values that should not change) Example: let name = "John"; const age = 25; var city = "Mumbai"; Keyword Scope Can Reassign Description var Function Yes Older and not recommended much let Block Yes Used when value can change const Block No Used when value should stay same JavaScript has two main types of data: String → "Hello" Number → 42, 3.14 Boolean → true or false Null → No value Undefined → Not assigned yet Symbol → Unique values (advanced) BigInt → Large numbers Object → {name: "John", age: 25} Array → ["apple", "banana"] Function → Reusable block of code Data types help the browser understand what kind of data we are using. A number is used for calculations. A string is used for text. A boolean is used for conditions (true or false). This helps JavaScript work smoothly and avoid errors.  ( 4 min )
    Why I believe 'dotnet run app.cs' Is a Huge Leap Forward
    C# is a beautiful language, rich with so many powerful features and possibilities. Over the years, I've used it to build a wide range of applications, and it's been incredible to watch the language evolve and grow.

    Quadratic AI now supports formatting
    Quadratic AI now supports formatting; AI can intelligently apply much of the same formatting you otherwise would have access to. With support for: Text styling: bold, italic, underline, strikethrough Alignment and text wrapping Applying color to text and cell backgrounds Number formatting: commas, currencies, percentages, date/time formatting Below are some scenarios that showcase the power of this feature. Broad formatting requests Have a sheet that could use a touch-up? Tell the AI to format your sheet however it thinks best. Format at specific locations Have a more opinionated location for your formatting? Tell the AI precisely where you’d like the formatting applied, and the AI will have an especially efficient time applying accurate formatting across the locations you define. Conditional formatting This action will usually be very accurate, but performance will degrade as you ask the AI to format larger and larger swathes of data. Expect accuracy up to hundreds or sometimes thousands of rows of data at a time. Quadratic AI, now supporting formatting The above are just a few possible examples of AI + formatting. Much more is possible with this feature; we can’t wait to see where else you’ll take it.  ( 3 min )

In Minnesota and across the country, more people are choosing natural wreaths to decorate their doors, walls, and windows. But why are natural winter wreaths trending this year? Let’s find out! Winter can sometimes feel dull and gray, especially in places like Minnesota where the trees lose their leaves and snow covers the ground. This is why many people want to bring a bit of nature into their homes. A natural winter wreath made of fresh greenery, pinecones, berries, and dried flowers adds life and color to any space. It reminds us of the beauty of the outdoors even whe…  ( 5 min )
    Stop Wasting Time on CSS Box Shadows - This Visual Tool Changed Everything
    After doing this dance for the hundredth time, I finally snapped and decided to build something that would save me (and hopefully you) from this tedious process. The Problem Every Frontend Dev Knows We've all been there. You need a nice shadow for a button, card, or modal. So you either: Copy from Stack Overflow - Hope those box-shadow: 0 4px 8px rgba(0,0,0,0.1) values work with your design Trial and error in DevTools - Spend way too long adjusting values until something looks right Ask the designer - "Hey, can you give me the exact shadow specs?" (if you're lucky enough to have a designer) The worst part? You never remember the values you used last time, so you repeat this process for every single project. As a developer, I wanted something that would: Let me see changes instantly (no ref…  ( 5 min )
    Tipado genérico en acción: implementando una tabla en React con TypeScript
    TypeScript permite definir tipos genéricos usando una sintaxis con , lo que funciona como una plantilla de tipo. Esto significa que podemos escribir funciones o componentes que no especifiquen de antemano un tipo fijo, sino que se adapten al tipo real de datos en cada uso. Por ejemplo, la función genérica function identidad(valor: T): T { return valor; } devuelve lo que recibe, y el compilador infiere el tipo concreto en cada llamada. En palabras de GeeksforGeeks, “los genéricos en TypeScript permiten crear componentes o funciones dinámicos y reutilizables que pueden manejar distintos tipos de datos manteniendo una estricta seguridad de tipos”. Es decir, los genéricos mantienen la seguridad del tipado (evitan errores de tipo en tiempo de ejecución) y al mismo tiempo aumentan la flexi…  ( 9 min )
    📲 Integrating Twilio into your project: Part 2 - Setting up the Sandbox and Handling Webhooks
    1. Joining the Twilio Sandbox Before you can start receiving messages via Webhook, you need to join the WhatsApp Sandbox. Here's how: In your Twilio Console, navigate to Messaging > Try it Out > Send a WhatsApp message. You’ll see a Sandbox section. Send the provided code (something like "join magic-pizza") to the given WhatsApp number. In my case, it was "join control-type". ✅ Done! Your phone is now linked to the Sandbox. Important: Next, you’ll tell Twilio where to send incoming messages. In the Sandbox settings, set your Webhook URL for incoming messages (e.g., https://yourdomain.com/webhook). You can do this on the same page, under the "Sandbox Settings" tab. Make sure your server can accept POST requests from Twilio. Now, every time that phone number receives a WhatsApp message, Twilio will send the message to your webhook so you can handle the incoming message. Twilio will send a payload like this: { "SmsMessageSid": "SMc8df133659ef2ca4251da5b1ac5453cdg", "NumMedia": "0", "ProfileName": "John Smith", "MessageType": "text", "SmsSid": "SMc8df133659ef2ca4251da5b1ac5453cdg", "WaId": "+157822787582693", "SmsStatus": "received", "Body": "The body of the message that you are receiving", "To": "whatsapp:+157822787584443", "NumSegments": "1", "ReferralNumMedia": "0", "MessageSid": "SMc8df133659ef2ca4251da5b1ac5453cdg", "AccountSid": "youraccountId", "From": "whatsapp:+157822787582693", "ApiVersion": "2010-04-01" } We'll code a real webhook handler in the next part 😉  ( 4 min )
    Architecture: Document architecture in a way that everyone understands
    In the world of backend development and designing complex systems, it's not enough just to write good code — it's equally important to clearly communicate architectural ideas to your team, clients, or new developers joining the project. One of the most effective tools for this is the C4 Model — a simple yet powerful way to document and visualize software architecture. Created by Simon Brown, the C4 model offers a hierarchical approach to diagramming, allowing you to gradually zoom in from broad concepts to detailed implementation. The model consists of four levels: System Context Containers Components Code What makes it especially convenient is that C4 is often used together with PlantUML, a powerful text-based tool for creating UML diagrams. This allows you to describe your system structu…  ( 7 min )
    Real-Time Data Without WebSocket Overhead
    Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first-of-its-kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand, and use APIs in large tech infrastructures with ease. If you've ever built something like a live score ticker, stock updates, or notification feed, chances are you've needed real-time updates from your server. While WebSockets often steal the spotlight, there's a quieter but super-effective player on the field: Server-Sent Events (SSE). Let's break it down and show you how to implement it from scratch using just HTML + JavaScript + a simple backend. Server-Sent Events (SSE) enable one-way, real-time communication from the server to the browser, using a single long-lived HTTP connection. Ke…  ( 5 min )
    The Cleanest Way to Add Optional Properties in JavaScript
    We've all done this: const payload = { action_type: event.actionType, }; if (event.contextLabel) { payload.label = event.contextLabel; } Or: const payload = Object.assign( { action_type: event.actionType, }, event.contextLabel ? { label: event.contextLabel } : {} ); But there's a better way, more concise, safe, and expressive: const payload = { action_type: event.actionType, ...(event.contextLabel && { label: event.contextLabel }), }; The && operator short-circuits. If contextLabel is falsy, nothing gets spread. If it's truthy, { label: value } is merged into the object. No mutations, no conditionals. Just structure. Make sure contextLabel is optional in your type definition: type UserActionEvent = { actionType: string; contextLabel?: string; }; When constructing payloads for analytics, logging, or API calls. When working with dynamic form data. When building clean utility functions. Clean code is not about writing less, it’s about making the intent obvious. This pattern removes clutter while keeping flexibility. Try it in your next project and let your code breathe.  ( 3 min )

    Automating APISIX TLS Secrets with CertManager using Argo Events: A Hands-On Guide
    When it comes to managing APIs in Kubernetes, APISIX offers a powerful and flexible platform. Recently, I encountered a unique challenge while integrating TLS certificates with APISIX,specially when automating certificate updates managed by cert-manager. cert-manager generates secrets in a standardized format (tls.crt, tls.key, ca.crt), but APISIX expects a different format: (cert, key) - ApisixTls CRD. Here's my journey and the solution that eventually worked, with Argo Events providing a real-time, automated workflow. Challenge: cert-manager automatically generates and renews certificates but stores them in a Kubernetes Secret object with keys like tls.crt and tls.key. However, APISIX requires a specific format - a Kubernetes secret with keys named cert (for the certificate) and key (for…  ( 8 min )
    The two biggest networking mistakes when job searching: How to turn strangers into lasting connections
    The internet has lots of advice on networking that ranges from painfully self-evident to makes-you-feel-sleazy. But networking doesn’t have to be transactional, awkward, or burdensome. Your network is really just the people you already know. All the people—your mom’s coworker, your college roommate’s little sister, your old boss. And networking is simply the act of meeting new people through the people you already know. Informational interviews (Zoom or IRL) or coffee chats are traditional ways of doing this, but you can meet people anywhere (on the bus, at a party, buying groceries). There’s lots of useful advice out there on how to build and maintain relationships (and ideally you invest in this at times you aren’t job searching).

    8 Code Commandments for Saner Development
    Writing code is one thing. Maintaining it after 3 weeks, 3 teammates, and 300 Slack messages? That’s the real challenge. Over time, I started collecting small rules, not from books, but from real experience. Here are my personal Code Commandments: the ones I wish someone had shared with me earlier. Write code like someone else will maintain it. Because they will. And one day, that "someone" is you after two sleepless nights and a different mindset. If your code needs a diagram and a Slack explainer just to read, it's probably too clever. Aim for obvious over original. Feeling stuck is normal. But spinning your wheels for hours isn't: it’s a silent killer of momentum. Set a timer. After 20 minutes: explain the problem, what you tried, and ask for help.

    Understanding the @Configuration Annotation in Spring
    The @Configuration annotation indicates to Spring that the class has one or more @Bean methods. When starting the application context, Spring will look to these classes to load the Spring IoC container with the beans you define in those methods. It allows you to create custom beans and perform configurations (like when you use Spring Security) so that everything is ready to go when the application starts. It's a really simple and powerful annotation and is often combined with other annotations. @Configuration is a class-level annotation. So we can define a configuration class and create some bean methods like this: import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class MyConfiguration { private stat…  ( 5 min )

I am not going to debate the value of unit tests or any other part of the test pyramid. I will say that I have developed the habit of asking the agent to generate new unit tests, or even to compare what's been implemented versus existing unit tests, and to cover gaps. The value from that practice has been inconsistent. The majority of the generated unit tests are valuable, and they pass on the first time.

    You've Been Using @layer in Tailwind CSS Wrong This Whole Time
    If you're using Tailwind CSS with Next.js or other modern frameworks, you've likely come across directives like @layer base, @layer components, and @layer utilities. But what's the difference between them, and how should they be used? This article explains each of them with practical examples to help you better structure your styles using Tailwind. @layer base For global resets and initial styles This is the first layer loaded. Ideal for: Resetting styles Setting global fonts Basic element styles like body, h1, button, etc. @layer base { h1 { @apply text-3xl font-bold text-gray-900; } body { @apply bg-background text-foreground font-sans; } } @layer components For reusable components (buttons, cards, badges, etc.) Loaded after base and before utilities. Perfect for blocks of combined utility classes: @layer components { .btn { @apply px-4 py-2 bg-purple-600 text-white rounded-md; } .card { @apply shadow-md rounded-lg p-4 bg-white; } } @layer utilities For custom utilities The last layer to load. Best used for specific, override-style utilities: @layer utilities { .text-shadow { text-shadow: 1px 1px 2px rgba(0, 0, 0, 0.1); } .scrollbar-none { scrollbar-width: none; -ms-overflow-style: none; } } @layer base <- Global styles @layer components <- Reusable components @layer utilities <- Specific utilities (highest priority) Use each like this: base: for tag resets and global defaults components: for .btn, .card, .input, etc. utilities: for .text-shadow, .scroll-smooth, etc. @layer components { .promo-price { @apply text-purple-600 font-bold; } .add-button { @apply px-4 py-1 bg-gray-200 rounded text-sm font-medium; } } Have you been using them correctly?

    Understanding :host-context() in Angular
    Angular's default style encapsulation prevents styles from leaking into or out of components. But sometimes, you want your component to adapt based on context provided by external elements, such as a dark class on the element. This is where :host-context() comes in. :host-context()? The :host-context() pseudo-class in Angular allows a component’s style to react to ancestor elements outside the component’s view encapsulation boundary. It checks if the component is rendered inside an element matching the selector. :host-context(body.dark) { .container { background-color: #222; color: white; } } This means: "Apply this style if the component is somewhere inside a ." Theming (e.g. light/dark mode) Reacting to global classes or layout wrappers Making components context-aware ✅ :host-context() checks up the DOM tree, not down. ✅ It works with Angular's default ViewEncapsulation.Emulated. ❌ It does not work with ShadowDom encapsulation. ❌ Do not repeat the context selector inside the rule block. :host { .container { background: white; color: black; } } :host-context(body.dark) { .container { background: black; color: white; } } // ❌ Incorrect :host-context(body.dark) { .dark { background: black; } } This is wrong because .dark is already in the selector. You don't need to repeat it. Use :host-context() to style Angular components based on their ancestors, such as when a global dark class is added to the tag. It’s a powerful tool to make your components responsive to global layout or theming changes.  ( 3 min )

    Do You Plan Ahead or Figure out Programs as You Are Writing Them?
    I have been wondering if I should plan ahead everything I code in advance since I tend to figure out a program as I go. When I do anything frontend, I plan how I want the CSS image or the web page to look like before I even start to code though but apart from that, I pretty much jump into it right away. I admit it would probably have saved me some time if I had just sat back and planned out the desired outcome more before I started coding. Here is an interesting excerpt on the topic from Hackers and Painters by Paul Graham: For example, I was taught in college that one ought to figure out a program completely on paper before even going near a computer. I found that I did not program this way. I found that I liked to program sitting in front of a computer, not a piece of paper. Worse still, instead of patiently writing out a complete program and assuring myself it was correct, I tended to just spew out code that was hopelessly broken, and gradually beat it into shape. Debugging, I was taught, was a kind of final pass where you caught typos and oversights. The way I worked, it seemed like programming consisted of debugging. Do you follow a particular structure while you code? Do you plan ahead or figure out programs as you are writing them?  ( 4 min )
    Google Firestore with MongoDB compatibility
    In this series, I tested multiple MongoDB emulations on top of SQL databases, and all failed to be compatible with a simple query like listing the last orders for one product in one country: db.orders.find( { country_id: 1, order_details: { $elemMatch: { product_id: 15 } } } ).sort({ created_at: -1 }).limit(10) Those emulations are syntax-compatible, but not behavior-compatible when it comes to performance and scalability. With MongoDB, such query finds immediately the ten documents from the following index: db.orders.createIndex({ "country_id": 1, "order_details.product_id": 1, "created_at": -1 }); It is simple: you index for the equality predicates, on country and product, and add the creation date to get the keys ordered. That's how you guarantee predicta…  ( 8 min )
    Why is a Project Execution Plan important?
    Aligns the Team with Project Goals A Project Execution Plan (PEP) is essential in project management because it provides structure and clarity to all stakeholders involved. It aligns the project team with the overall goals, scope, and methodology, ensuring everyone is working toward the same objective. With a well-documented PEP, the project reduces the risk of miscommunication by outlining roles, responsibilities, timelines, and communication protocols. By clearly stating who is responsible for what and how updates or issues should be communicated, a PEP helps eliminate confusion. This clarity allows team members to focus on their tasks without second-guessing the process or duplicating efforts. The plan enhances accountability by defining each team member's duties, deadlines, and expected outcomes. This promotes commitment and productivity throughout the project lifecycle, as everyone understands their contributions and deliverables. With a structured timeline and monitoring procedures, a PEP acts as a roadmap for the project. It helps the team identify potential delays early, make necessary adjustments, and keep the work progressing smoothly. A PEP includes a detailed budget and resource plan, allowing project managers to monitor financial performance. This ensures that spending remains within approved limits and that resources are used efficiently throughout the project. Ultimately, the Project Execution Plan is crucial because it guides the team through every phase, ensuring that the project is delivered on time, within budget, and according to expectations. It acts as both a strategic and operational tool for successful execution.  ( 3 min )
    AI Editor Assistant
    Hey everyone! 👋 I just released a new tool on the Unity Asset Store that I’ve been working on for a while — it’s called AI Editor Assistant.

Basically, it's like having ChatGPT inside Unity. You can: Ask questions about your scripts Get explanations for complex code Generate boilerplate or new scripts Debug with a second pair of “AI eyes” Customize it to work with different APIs It’s designed for solo devs, students, and small teams who want to speed up development and reduce the back-and-forth between IDEs and AI tools. Would love to get your thoughts or suggestions! If you try it out, let me know what features you'd like to see added. https://assetstore.unity.com/packages/tools/ai-ml-integration/ai-editor-assistant-319644 Thanks for checking it out — and happy devving! 🎮🧠  ( 3 min )
    Baldur's Gate 3 devs originally went for a truly “cartoony” art style, but I'm glad they didn't go with it
    TL;DR: During early Baldur’s Gate 3 development, Larian Studios experimented with a cartoony, stylised “indie book” look—tearing the visuals down and restarting the art direction at least twice—before settling on the grounded, richly coloured style fans know today. Why it matters: Lead character artist Alena Dubrovina says those full turnarounds were brutal but ultimately paid off, giving BG3 a more realistic edge that likely helped its massive success. That said, the team’s animated shorts and indieish sketches are so charming that the author hopes one of Larian’s upcoming projects leans back into a fun, exaggerated cartoon vibe.  ( 3 min )
    OG Star Wars Battlefront devs were asked to make Battlefront 3 in just one year, but Pandemic couldn't hit LucasArts' timeline
    TL;DR: After smashing it with the original Battlefront games, Pandemic Studios quietly kicked off Battlefront 3 right after Part II’s release…but LucasArts only gave them a one-year deadline. With a massive leap to PS3/Xbox 360 hardware and no idea what those new consoles could really do, Pandemic couldn’t hit the timeline and talks fell apart. LucasArts then handed the project to Free Radical Design, who pushed their version to about 95% complete (complete with seamless space-to-ground battles), yet it too was canned. Pandemic folded in 2009, and aside from EA’s 2017 Battlefront II reboot, a bona fide Battlefront 3 still remains the stuff of fan dreams.  ( 3 min )

    Warhammer 40,000 Maker Games Workshop Is Doing So Well It's Giving $27 Million to Its Staff
    TL;DR Games Workshop—best known for its Warhammer 40K miniatures—is riding a massive boom, reporting £560 million in core revenue (up from £494.7 million) and £50 million in licensing revenue (vs. £31 million) for the year ending June 1, 2025. Profits soared too, with pre-tax earnings of £255 million (up from £203 million), prompting the company to hand out a £20 million bonus pool—around £13,333 (≈ $18,000) per staffer across its ~1,500 employees. Beyond tabletop sales, GW’s IP machine is humming: smash-hit games like Space Marine 2 (and Space Marine 3 in the pipeline), Amazon’s Secret Level animation, and a newly inked Henry Cavill–fronted Warhammer cinematic universe all helped lift licensing revenue to record highs. While they don’t expect this licensing surge to repeat next year, Warhammer’s never been bigger—and it doesn’t look like it’s slowing down anytime soon.  ( 3 min )

    The Rise of Multi-Agent AI: Where It’s Going and Why It Matters
    We’re witnessing the early stages of a paradigm shift in how AI systems are built and deployed. The era of single-agent chatbots is giving way to something much more powerful: multi-agent AI systems — where multiple intelligent agents collaborate, specialize, and reason together to solve complex tasks. From research labs to early-stage startups, multi-agent architectures are redefining how we think about productivity, orchestration, and scalable intelligence. As the field accelerates, it’s worth asking: Where is this going, and what does it mean for builders, teams, and the future of work?

    🎨 Bridging Designers and Developers: Stop Fighting Colors with Palette Box
    Collaboration between designers and frontend developers should be smooth. But when it comes to handling colors, it often looks like this: "Which blue did you use again?" If this sounds familiar, you're not alone. Designers work visually. Developers work semantically. In between? Miscommunication. Whether it's screenshots, Figma files, or style guides with missing tokens, developers are left trying to: Pick colors manually from images Match by eye (ouch) Guess naming conventions (or worse, ignore them) Palette Box is a lightweight Chrome extension that solves this handoff issue. It helps developers and designers: Drag across any area on a webpage Automatically extract visible colors Select and organize colors into meaningful presets Export them directly into code (JSON) Share presets securely Once you've selected the colors, you can rename them and export them as JSON. This is perfect for integrating with Tailwind configs, SCSS variables, or React themes. Example output: { "#71c0bb": "#71c0bb", "graygreen": "#4e6688" } Whether you're a designer defining visual language, or a developer implementing a component library, Palette Box helps you: Standardize color tokens Reduce feedback cycles Improve communication with shared presets Bonus: color naming is preserved and encrypted when shared. All basic extraction is free. That’s cheaper than your daily coffee ☕ — and way more useful. 🔗 → Install Palette Box from Chrome Web Store Save time. Reduce color miscommunication.

    Why Agile Teams Overcommit and How to Fix It
    Sprint planning is supposed to give you guardrails, clear, reasonable boundaries for what your team can actually deliver. But in practice? Most teams commit to 20–40% more work than they have the capacity to complete. Not because they’re lazy or bad at math—but because the system nudges them to do it. Here’s what’s really driving overcommitment (and how to fix it): Team members don’t feel safe pushing back. You’re measuring story points, not outcomes. You reward volume, not focus. Leadership derails the sprint mid-flight. You need micro rituals to reinforce this. Add these weekly nudges: 🟣Week 3: Mid-sprint confidence check (again, 1–5) Want to make this stick?

    🏢 Azure Regions & Zones
    What are Azure regions? Azure has over 60 regions worldwide, each made up of data centers and network systems. Regions are grouped by geography, like the U.S. or Europe, which sets rules for where data stays. An Azure region consists of one or more datacenters, connected by a high-capacity, fault-tolerant, low-latency network connection. Azure datacenters are typically located within a large metropolitan area. Every region is contained within a single geography that serves as a fixed data residency boundary. If you have data residency requirements, it's important that you select regions within the required geography. Each geography has at least one region equipped with availability zones.

    🖥️ Azure Virtual machines
    🤔 What is a virtual machine? In its simplest form, a virtual machine, or VM, is a digitized version of a physical computer. Virtual machines can run programs and operating systems, store data, connect to networks, and do other computing functions. However, a VM uses entirely virtual resources instead of physical components. VMs enable businesses to create isolated environments on host hardware that behave like separate machines. A more straightforward way to understand what a virtual machine is to think of it as a virtual computer within another computer. But instead of a physical computer like a server, laptop, or smartphone, a VM is defined by software. Virtual machines use virtualization technology to create virtual hardware—or a virtual version of a computer on a physical machine.…  ( 4 min )

    What is RAG (Retrieval- Augumented Generation)
    RAG allows the AI model to look things up before answering a question. RAG is an AI technique that combines two powerful components: 1. A retriever that searches for relevant information from external sources 2. A generator (like GPT or Claude or any other AI model) that uses that information to craft accurate, grounded responses RAG is used in scenarios such as: Recent data or information is required to answer a question Information needs to be retrieved from private documents Let’s say you ask an AI assistant: “What’s our company’s refund policy?” The question is converted into a vector (a list of numbers that captures the meaning) It searches a vector database of your documents (like PDFs, FAQs, or manuals) It retrieves the most relevant chunks of text It inserts those chunks into the prompt sent to the language model The model then generates an answer based on both your question and the retrieved info 1.Split Documents into Chunks (Document Chunking) Example Chunk: “Employees are eligible for health benefits after 90 days of full-time employment…” 2.Generate Embeddings (Using Embedding Model) The more dimensions, the more nuance the vector can represent — like tone, topic, or context. Example Chunk vector → 0.21, -0.64, 0.48, …, 0.02 3.Store in Vector Database Now your database can search by meaning, not just keywords. ⸻ RUNTIME (When User Asks a Question) ⸻ 4.User Asks a Question “When do I qualify for health benefits?” 5.Convert Question to a Vector (Query Embedding) 6.Semantic Search in Vector DB Retrieved chunk: “Employees are eligible for health benefits after 90 days…” 7.Augment the Prompt Prompt to the foundation model: Context: Question: 8.Foundation Model Generates Answer “You qualify for health benefits after 90 days of full-time employment, according to company policy.” No fine-tuning needed: You don’t have to retrain the model Up-to-date answers: Pull from the latest documents Custom knowledge: Use your own files, policies, or FAQs Fewer hallucinations: Grounded responses using real data  ( 4 min )

    Using Tuples in Typescript
    In TypeScript, a tuple allows you to describe a structured array, where the position of each element is meaningful and dictates what type each is expected to be. For example, you might use a tuple to store the data associated with a User type. You could declare this type mandating that the first value in a User tuple must be a number (representing the user's id), and the second a string (representing their displayName). // Declaring a User type consisting of an array with // a number at `[0]` followed by a string at `[1]` type User = [number, string]; const Alice: User = [123, 'Alice']; // OK const Bob: User = ['Bob']; // ERROR Type 'string' is not assignable to type 'number'. try in playground You could make this more explicit by using named tuple elements in your type declaration.

    Best Practice: Rate Limiter in API
    When designing an API, the important thing to keep in mind is the ethical usage of the API. If the API is provided as a third party service i.e. protected via a token it is possible that it can be misused by too frequent access. Further, if your API is public, there is chance that bots could hit it continuously and cause high usage of server resources. To cater to all of this we need a mechanism to check the number of requests made. express-rate-limiter is an npm package that allows us to do so. By adding this middleware we restrict IPs from accessing a/all routes to n times per minute/second. // rate-limiter.middleware.ts import rateLimit from 'express-rate-limit'; export const rateLimiter = rateLimit({ windowMs: 1 * 60 * 1000, // 1 minutes max: 100, // Limit each IP to 100 requests per windowMs standardHeaders: true, // Return rate limit info in the `RateLimit-*` headers legacyHeaders: false, // Disable the `X-RateLimit-*` headers }); This middleware basically says that each IP is restricted to make up to 100 requests every minute. More than that it throws a 429-Too Many Requests error. // in app.ts app.use(rateLimiter); For the first 100 requests across your API endpoints, it works fine. The 101st one throws a 429 error. Once the minute is passed it reverts back and you can make 100 requests again. This way you have prevented too many hits to your server.  ( 3 min )

    The Hidden Performance Pitfalls of EF Core LINQ Queries
    The Good Part Entity Framework Core (EF Core) is a popular Object-Relational Mapper (ORM) that simplifies data access in .NET applications by allowing developers to use LINQ (Language Integrated Query) for interacting with databases. This abstraction provides strong typing, compile-time checking, and a more readable syntax than raw SQL. The Problem Developers find it easy to write a LINQ query to fetch results from database with the built-in intellisense support. However, beneath this convenience lies a critical challenge: EF Core translates LINQ queries into SQL at runtime, often producing complex and inefficient SQL queries that can severely degrade database performance. EF Core LINQ queries are translated into SQL at runtime, often resulting in inefficient and bloated SQL. Developer…  ( 4 min )
    What is Staff Augmentation? A Comprehensive Guide to IT Talent Sourcing
    In simple words, staff augmentation means bringing in skilled professionals to work with your in-house team for a specific project or need to augment the capacity of your workforce. But why is there so much hype around staff augmentation these days? Why is everyone suddenly talking about IT staff augmentation, and why is it becoming such a popular topic in software development circles? To understand this, you have to take a couple of steps back and look at why staff augmentation exists in the first place. Actually, when companies hire, they hire based on a few variables. These variables include workload projections, available in-house talent, budgets, and timelines. But the reality is that these variables can shift, sometimes halfway through a project. For instance, your product launch …  ( 21 min )
    I Built a Game in Under an Hour with Amazon Q CLI (and Here's What Happened)
    The challenge was set: Build a game using the Amazon Q CLI for a shot at scoring a coveted T-shirt. As a developer always up for a new challenge, I dove in headfirst. My goal? To create a functional shooting game in under an hour, relying solely on the command line and Amazon's new AI assistant. The result was a whirlwind of rapid development, unexpected hurdles, and a revealing glimpse into the future of coding. My initial thought was to keep my development environment clean and containerized using Docker. However, I quickly hit a roadblock. The game I envisioned, a dynamic shooter, would be built with Pygame, a popular Python library for game development. Pygame, by its nature, requires a graphical interface to render the game window, something my Docker setup wasn't configured for. P…  ( 5 min )
    Why “Autonomous” AI Tools Still Need a Babysitter
    Most “autonomous” AI tools are just brittle workflows hiding the UI. They break on edge cases, need constant nudging, and definitely aren't running your business solo. If your “autonomous AI tool” breaks the moment you walk away, congrats: you’ve built a toddler with an API key. This isn’t autonomy. It’s automated anxiety. Everyone’s slapping “self-running” or “copilot” on tools that still need human oversight, decision correction, and manual retries. Let’s talk about what real autonomy actually means — and why most tools today aren’t even close.

    🚀 Getting Started with TypeScript in Deno
    If you're new to Deno, one of the best parts is that it supports TypeScript out of the box — no extra config, no bundlers, no headaches. In this post, I'll walk you through why TypeScript is a game-changer and how Deno makes it easy to start using right away. TypeScript is a statically typed superset of JavaScript. It helps you write safer code by detecting bugs before your code runs. And best of all — with Deno, you don’t need a build step or tsconfig.json to get started. Native TypeScript support: Just use .ts files and Deno handles the rest Cleaner project setup: No need for Babel, Webpack, or tsc Improved tooling: Built-in formatter, linter, and test runner — all work with TS Secure by default: Deno runs in a sandbox unless explicitly allowed // hello.ts function greet(name: string): string { return `Hello, ${name}!`; } console.log(greet("Deno + TypeScript")); Run it directly: deno run hello.ts Boom — TypeScript without any setup. Use Deno’s built-in module system: // utils.ts export function square(x: number): number { return x * x; } and import in another file // main.ts import { square } from "./utils.ts"; console.log(square(4)); // 16 In the next posts, I’ll cover: Organizing a Deno project with TypeScript Using third-party modules with type definitions Testing with Deno’s built-in test runner Deploying TypeScript APIs with Deno Deploy -- deno doc your_module.ts Thanks for reading! --- Let me know if you’d like a follow-up post — for example, setting up a REST API in Deno with full TypeScript types.  ( 4 min )

    Serverless Backend: A New Era for Developers
    As Developers, we’ve all been in this situation, using node index.js to start an Express server on port 3000. This method has proved useful for some time, but making it work in production takes a lot of effort. In traditional deployment, you select a cloud provider such as AWS, GCP, Azure or Cloudflare, rent virtual machines and start to deal with operational problems like: Using Auto Scaling Groups or Kubernetes to manage scaling in a complex way Charging for idle resources when there is little traffic Regular watch over server conditions and maintenance Need to manually deploy and restart after changing the code Organizing what to do during unexpected downtime and failures These problems take our focus away from the main thing we enjoy, creating code that solves real issues.

    # Why I Was Inspired by Cloud Native and DevOps
    Not long ago, I was writing code, deploying manually, and firefighting issues in production. It worked — until it didn’t. I didn’t realize there was a better way until I came across two transformative ideas: Cloud Native and DevOps. My journey into Cloud Native and DevOps started when I hit a wall with traditional infrastructure. Deployments were risky. Rollbacks were messy. Scaling? Not without downtime. Then I saw a demo of Kubernetes. Followed by someone showing how CI/CD pipelines could auto-deploy code into production — with tests and rollback strategies baked in. It felt like the software was finally working with me, not against me. Automation is Freedom Seeing repetitive tasks like testing, building, and deployment become fully automated showed me how much time and mental space we waste doing things machines can do better. Cloud Native = Resilience at Scale Containerized workloads, microservices, and declarative infrastructure helped me realize how modern systems can be self-healing, portable, and easier to scale. DevOps = Collaboration Over Silos No more "dev vs ops." DevOps taught me that when teams share responsibility — from development to deployment — software becomes more reliable and teams work better together. It’s not about tools; it’s about mindset. Cloud Native isn’t just Kubernetes. It’s how we design systems to be scalable, resilient, and observable. DevOps isn’t just CI/CD. It’s about breaking barriers between teams, improving feedback loops, and embracing continuous improvement. Are you exploring Cloud Native or DevOps? I'd love to hear what inspired you, what tools or concepts changed your mindset, or what challenges you’re facing. Let’s connect in the comments! Thanks for reading! You can follow me for more posts on DevOps, Cloud Native, and how modern infrastructure is reshaping software engineering.  ( 4 min )
    HarmonyOS 5 Cangjie Macro Programming Basics: From Procedural Macros to Template Macros
    As a developer who has deeply used HarmonyOS 5 in multiple large-scale projects, I must say that the macro system of the Cangjie language is one of the most elegant metaprogramming solutions I've ever seen. It is neither as "simple and crude" as C macros nor as "profound and obscure" as Rust macros. This article will take you deep into the core of this macro system and share our best practices in actual projects. In a distributed computing module, we designed an intelligent debugging macro: public macro DebugLog(expr: Tokens) { return quote { if $LogLevel >= DEBUG { let __start = Clock.now() let __result = ${expr} println("[DEBUG] ${stringify(expr)} = ${__result}, took ${Clock.now() - __start}ns") __result …  ( 4 min )
    HarmonyOS 5 Cangjie Language Anti-Reverse Engineering Practice: Obfuscation Techniques and Security Hardening
    This article explores in depth the anti-reverse engineering capabilities of Huawei's HarmonyOS 5 system, focusing on the Cangjie language's obfuscation and hardening techniques. The content is based on actual development practices and aims to serve as a resource for technical exchange.

    Is Apple Really Protecting Us? A Look at Android’s Open App Stores and Their Security Record
    Apple has long defended its refusal to allow third-party app stores on iOS with one word: security. According to the company, restricting app installations to the App Store is the only way to protect users from malware, scams, and unsafe behavior. But there’s a counterexample that’s been running for over a decade: Android. On Android, users can freely install apps from other stores—Amazon Appstore, APKPure, F-Droid, Uptodown, Aurora Store, and more. These platforms are not only legal and operational; they also serve millions of users every month. So the question becomes: If third-party stores are so dangerous, why hasn’t Android collapsed under the weight of malware? The Android Reality: Open Doesn’t Mean Unsafe Yes, Android is more open.

    JavaScript Shortcuts, Tips & Tricks — Simple & Fun Examples for Everyone
    Hey there! If you’re learning JavaScript or just want to code smarter (not harder), I’ve got some handy tips and tricks with examples that are easy to get — and maybe even a little fun. Ready to speed up your JavaScript game? Let’s jump in! const hungry = true; const food = hungry ? 'Order pizza!' : 'Keep coding!'; console.log(food); // Order pizza! Why? function gift(name = 'Friend') { console.log(`Here’s a gift for you, ${name}!`); } gift(); // Here’s a gift for you, Friend! gift('Alex'); // Here’s a gift for you, Alex! Why? const person = { firstName: 'Sam', lastName: 'Smith', age: 25 }; const { firstName, age } = person; console.log(`${firstName} is ${age} years old.`); // Sam is 25 years old. Why? const pet = 'dog'; const petName = 'Buddy'; const sentence = `My ${pet} is called ${petName} and he loves belly rubs.`; console.log(sentence); Why? const multiply = (x, y) => x * y; console.log(multiply(4, 5)); // 20 Why? const userInput = ''; const defaultText = userInput || 'Please type something!'; console.log(defaultText); // Please type something! Why? const veggies = ['carrot', 'broccoli']; const moreVeggies = [...veggies, 'spinach']; console.log(moreVeggies); // ['carrot', 'broccoli', 'spinach'] Why? const scores = [3, 6, 9]; const funScores = scores.map(score => `You scored ${score} points! Yay!`); console.log(funScores); Why? const car = { model: 'Tesla' }; console.log(car.owner?.name || 'Owner unknown'); // Owner unknown Why? const snacks = ['chips', 'cookies', 'pretzels']; for (const snack of snacks) { console.log(`I love ${snack}!`); } Why?

    Can Artificial Intelligence Really Beat the Stock Market Over Time?
    There’s an old joke about the stock market: If you want to make a small fortune, start with a large one. It’s the kind of gallows humor that traders sip their tea over, staring out at the flickering screens of their Bloomberg terminals. But in our age of algorithms and all-powerful machine learning models, the old wisdom is being rewritten — or at least, that’s what the quants would like us to believe. The idea that artificial intelligence can consistently beat the market is both seductive and, frankly, a little terrifying. Because if it’s true, then what are we doing here, with our frantic chart analysis, our fevered option plays, our futile attempts to time the Fed’s next move? Let’s start with a dose of humility (which, let’s be honest, the financial world could use a bit more of). AI, or at least the kind we worship today, isn’t some all-knowing oracle whispering stock picks from the depths of a silicon godhead. It’s math. Really complicated, computationally expensive math, but math nonetheless. And as any philosophy student who spent too much time reading Sartre in a college library can tell you, math does indeed have limits. 🤖 The Rise of AI in Trading These systems excel in: Speed: Executing trades in milliseconds to capitalize on fleeting opportunities. Downtrend Markets: AI-driven funds have demonstrated superior risk-adjusted performance during market downturns, effectively mitigating downside risks. 🧠 Limitations of AI in Trading Overfitting: AI models trained on historical data may not adapt well to unforeseen market events. Augmented Decision-Making: AI can handle data-heavy tasks, allowing humans to focus on strategic decisions.

    AI Personalization: The Future of Customer Experience (CX)
    When you hear the phrase “customer-first,” you likely think of a business approach centered on human empathy and personal interaction, not automated systems or AI-driven processes. After all, customer experience is about people, right? But here’s the twist: the reality is that AI personalization is now emerging as the core strategy behind truly customer-first. Without AI, delivering truly personalized experiences at scale is nearly impossible.  Whether you’re developing e-commerce apps, running targeted ad campaigns, or optimizing customer journeys, applying AI personalization can deliver breakthrough results. Leveraging AI-powered insights and automation has become a critical requirement for driving real customer engagement and sustainable growth.  So, in this blog, we’ll explore how AI P…  ( 10 min )
    Library Vs Framework
    The difference between a library and a framework lies mainly in the control of flow and how they are used in your code. Library ➤ Definition: A library is a collection of pre-written code that you can call and use whenever you need in your application. You are in control: You call the library’s functions. Focused on specific functionality (e.g., math, logging, database). Can be used in any part of your code. In Java: import java.util.ArrayList; ArrayList list = new ArrayList(); list.add("Hello"); list.add("World"); You call add() from the ArrayList library — you are in control. Framework ➤ Definition: A framework is a complete structure where your code fits in predefined places. The framework controls the flow and calls your code when needed. Inversion of Control (IoC): The framework calls your code, not the other way around. Provides a skeleton; you fill in the blanks. Often used for larger systems (e.g., web apps, enterprise systems). In Spring Framework: @RestController public class HelloController { @GetMapping("/hello") public String sayHello() { return "Hello from Spring"; } } Here, Spring controls the flow — it decides when and how to call sayHello(). Feature Library Framework Control Flow You control the flow Framework controls the flow Usage Call functions when needed Plug your code into framework Purpose Specific functionality Application structure Examples (Java) Apache Commons, Gson, JUnit Spring, Hibernate, Java EE Flexibility More flexible More rules and structure Library: A toolbox — you take the tools you need and use them however you want. Framework: A machine — you insert your parts into the machine, and it runs the process.

    J1SE (Java 1 Standard Edition) VS J2EE (Java 2 Enterprise Edition)
    The difference between J1SE (Java 1 Standard Edition) and J2EE (Java 2 Enterprise Edition) lies mainly in their purpose and features: J1SE (Java 1 Standard Edition) Now called Java SE (Standard Edition) Provides the core functionality for Java programming. It’s used to develop general-purpose desktop applications. Core Java libraries (java.lang, java.util, java.io, etc.) OOP principles Collections, Streams Multithreading Networking JDBC (Java Database Connectivity) GUI (AWT, Swing, JavaFX) Standalone applications Desktop tools Command-line programs Games or utilities J2EE (Java 2 Enterprise Edition) Now called Java EE (Enterprise Edition), and currently known as Jakarta EE Extends Java SE to provide tools for building distributed, multi-tier, scalable, and enterprise-level applications. Servlets & JSP (Java Web Applications) EJB (Enterprise Java Beans) JPA (Java Persistence API) JMS (Java Messaging Service) Web Services (SOAP, REST) JTA (Java Transaction API) JNDI (Java Naming and Directory Interface) Security, scalability, and transaction management Web applications Enterprise applications (banking, ERP, CRM) APIs and Microservices Large-scale distributed systems Key Differences Summary Feature Java SE (J1SE) Java EE (J2EE) Scope Core Java (basic programming) Enterprise features built on Java SE Target Desktop/standalone apps Web & enterprise apps Libraries/APIs Basic Java classes Servlets, JSP, EJB, JPA, JMS, etc. Platform Single-tier Multi-tier (Web, Business, Data) Complexity Simpler More complex Application Server Required ❌ No ✅ Yes (e.g., Tomcat, GlassFish, JBoss) Java SE = Foundation / Core tools Java EE = Built on top of Java SE, adds enterprise capabilities for building large-scale, web-based, and distributed systems. If you're starting out, you typically begin with Java SE, then move to Java EE (or Spring Framework) as you build enterprise applications.

    What is home healthcare scheduling software? (Simple But Powerful)
    Home healthcare scheduling software is a specialized tool that helps care agencies assign, track, and manage caregiver visits in patients’ homes. It essentially acts as a digital scheduling assistant: coordinating appointments, assigning the right caregiver based on skills and location, and sending reminders. This software is needed because scheduling home visits manually (via spreadsheets or phone calls) is complex and error-prone. By centralizing scheduling tasks, it ensures the right caregiver is matched with the right patient at the right time. Many systems even provide mobile apps and online portals so staff, caregivers, and patients can view and update schedules on the go, keeping everyone on the same page. Home care agencies manage dozens of caregivers and clients across many locations, and “having a reliable scheduler is the heart of running an efficient operation and providing high-quality care”. Without scheduling software, agencies can face double-bookings, gaps in care, and wasted travel time. A modern scheduling solution automates these tasks and cuts paperwork: for example, it can handle appointment booking, staff availability, and even billing in one system. In practice this means caregivers spend less time on admin and more time caring for patients. For example, software that automates provider schedules dramatically reduces double-bookings and other common errors. In short, home healthcare scheduling software is needed to streamline operations, improve accuracy, and ensure patients get timely visits without administrative headaches.  ( 3 min )

    Trade Policy & Economic Reform
    The goal to reform the global trading system stems from persistent dollar overvaluation that creates economic imbalances by making it costly for the U.S. to provide reserve assets and defense while hurting American manufacturing. This analysis examines policy tools available to reshape international trade and financial systems, finding that tariffs can generate revenue with minimal adverse effects when offset by currency adjustments—essentially making tariffed nations finance the costs while improving burden-sharing for reserve asset provision. The study explores both multilateral and unilateral approaches to currency policy, optimal tariff implementation strategies intertwined with national security concerns, and the sequencing of these reforms to minimize market volatility, concluding that significant generational changes to the international economic system are possible through careful policy coordination.

    Learning Amazon EventBridge - Notes by Archies Gurav
    Hello everyone, So, recently I have been learning Amazon EventBridge as part of my continuous cloud learning journey. I'm a DevOps engineer exploring how we can build event-driven architecture on AWS, and EventBridge felt like one of those underrated tools that deserves more spotlight. In this post, I'll walk you through what things I have learned about Amazon EventBridge in simple words. Before directly learning about the tool, I first understood the concept of Event-Driven Architecture, like exactly what is it. -> In simple words, Event-Driven-Architecture is a software design pattern where services communicates asynchronously through events, allowing for flexibility or loose coupling. You may think that okay, we got the concept of EDA, but what is an event actually here in EDA.. -> In …  ( 5 min )
    Debugging Docker? You’re Probably Missing This Hidden Gem
    Everyone uses Docker, but almost no one knows how to really debug a container. No, I’m not talking about the usual suspects: `docker logs` → often empty or useless `docker inspect` → static snapshot `docker exec` → can’t attach before the container dies Sound familiar? When your container crashes in production (but works fine locally), you end up in a loop: tweaking the Dockerfile, redeploying, and praying. But there’s a better way. docker events – The Secret Weapon This little-known command streams real-time, low-level events straight from the Docker daemon. It exposes what docker logs won’t tell you. Your container keeps restarting. The logs show nothing. Instead of guessing, run: docker events --filter container= 2025-05-04T18:20:01Z container create ... 2025-05-04T18:20:02Z container start ... 2025-05-04T18:20:03Z container health_status: unhealthy ... 2025-05-04T18:20:04Z container kill signal=SIGTERM 2025-05-04T18:20:04Z container restart Boom. Now you see: Health check failed → Container killed → Docker auto-restarted it Your app logs? They won’t show this. The health check runs outside your main process. Filter by time: docker events --filter contaner= --since="30m" --until "2025-05-04T18:00:00" docker events --filter container= --since="5m" --format '{{json .}}' | jq But What About Observability Tools? Sure, Grafana, Prometheus, and Loki are great. But they won’t catch: OOM kills before metrics are scraped Failed volume mounts Init containers that crash silently Sidecars restarting in the background docker events sees everything—in real time.

    Deepfake : entre prouesse technique et enjeux de confiance numérique
    L’image n’a jamais été aussi malléable qu’aujourd’hui. Ce que l’on voit n’est plus nécessairement ce qui a été filmé, et l’émergence du deepfake cristallise ce bouleversement. En associant intelligence artificielle et traitement vidéo, cette technologie permet de générer des visages, des gestes ou des voix avec un réalisme qui défie la perception. D’abord développée pour des usages ludiques ou créatifs, elle s’est rapidement propagée à d’autres sphères : politique, médiatique, sociale. Si la prouesse technique impressionne, elle interroge surtout nos filtres d’analyse. Peut-on encore faire confiance à une vidéo ? À un visage ? À une émotion ?

    What Is a Reverse Proxy? A Developer-Friendly Guide
    If you've ever deployed a modern web app, chances are you've used a reverse proxy—even if you didn’t know it. So, what is a reverse proxy? And why is it such a critical piece of today’s web infrastructure? Let’s break it down. Before diving deeper, here’s a quick comparison: Forward Proxy: Used by clients (like your browser) to access the internet. Think of it as a middleman that hides your IP or bypasses content filters. Reverse Proxy: Used by servers to handle incoming requests. It stands in front of one or more backend servers and acts as a gateway. A reverse proxy sits between the client and your backend servers, accepting incoming traffic and forwarding it appropriately. It can: Balance load between multiple backend servers Handle SSL termination (HTTPS) Act as a caching layer Protect…  ( 4 min )

    From Fog to Clarity: 4 Months as a Solo SaaS Founder
    I’ve always wanted more freedom—time, money, and people who get where I’m coming from. That’s what pushed me to go solo, but I’d be lying if I said I knew what I was getting into. This wasn’t my first shot. My last project, a financial app, ended when my cofounder and I split over the direction. Looking back, I threw everything I knew at it: Spring Boot backend, Next.js frontend, Elasticsearch, Postgres, Redis, all Dockerized. At the time, I thought that was what “real” startups did. But honestly? I spent more time configuring services than shipping anything useful. When it all fell apart, I realized I was building complexity, not momentum. Lesson #1: Simple wins. This time, I picked the T3 stack. One repo, one server, straight to Vercel—suddenly, I was actually building features instead o…  ( 4 min )
    Defect Triage in Software Testing
    Triage Meaning in Software The main goal is to ensure that the most critical defects are addressed promptly while deferring or even rejecting low-impact issues that don’t threaten the product’s stability or customer satisfaction. Why Do You Need a Defect Triage? Efficient Use of Resources: Focus development and testing efforts on defects that truly matter. Better Decision Making: Enables data-driven discussions about whether to fix, defer, or reject a defect. Improved Communication: Aligns all stakeholders on defect status and resolution plans. Quality Control: Helps maintain a healthy and manageable defect backlog. How Often Should You Have Defect Triage? Daily during active development or release cycles. The Defect Triage Meeting Review new and existing defects. Defect Triage Process Gather Defects: Collect all open or newly reported defects since the last triage. Review & Clarify: Ensure all bugs have complete, understandable, and reproducible steps. Assess Severity & Priority: Classify based on business impact and urgency. Assign Ownership: Designate responsible developers or teams. Set Resolution Plan: Define when and how the bug should be addressed (fix immediately, delay, or reject). Challenges with Defect Triaging Subjectivity: Different stakeholders may have conflicting views on a bug’s severity. Volume Overload: Too many bugs can overwhelm the team and delay decisions. Incomplete Information: Poorly reported bugs slow down the triage process. Lack of Accountability: Unclear ownership can result in unresolved or orphaned defects. Time Constraints: In fast-paced sprints, teams may skip triage, leading to chaos later. Thumb Rules in Bug Triage Fix high-severity and high-priority bugs first. Conclusion By incorporating intelligent platforms like GenQE.ai, teams can elevate their defect triage process with automation, pattern recognition, and smart prioritization, making software testing more efficient and outcomes more predictable.  ( 4 min )

    7 Best Data Integration Platforms: Reviews & Top Picks
    Originally published at https://www.nocobase.com/en/blog/data-integration-platforms. In today's digital enterprises, "data silos" remain a pervasive challenge. A single customer may have records in CRM, support tickets in the helpdesk system, and transactions in the payment gateway—but these data points often exist in isolation, making it impossible to drive automated actions or gain unified insights. Many organizations resort to manual Excel exports, custom scripts, or system-by-system integrations just to facilitate basic business workflows. This fragmentation of data has become one of the biggest hurdles to digital transformation. This is where Data Integration Platforms come in. Their core value lies in connecting internal and external systems, ensuring data flows to the right place, a…  ( 5 min )

    Coroutine - Kotlin
    Coroutine - Kotlin A coroutine is a programming construct that allows a function to suspend its execution and resume it later, enabling cooperative multitasking and asynchronous programming Coroutines don't preemptively switch between tasks; they voluntarily yield control (suspend) to allow other tasks to run. This cooperative nature enables coroutines to perform tasks without blocking the main thread or other operations, making them suitable for UI-related tasks and I/O operations. Coroutines maintain their state between suspensions, allowing them to resume where they left off. Coroutines use special keywords or mechanisms (like await in Python or yield in Unity) to suspend their execution and resume later when needed. Coroutines provide a cleaner and more readable way to handle asynchronous operations compared to traditional callbacks or promises. Coroutines can help organize complex asynchronous logic, making it easier to understand and maintain. Coroutines are lightweight and don't require the overhead of creating and managing multiple threads. In some cases, coroutines can provide the illusion of concurrency without the need for actual threads, improving efficiency. import kotlinx.coroutines.* fun main() = runBlocking { println("Main starts: ${Thread.currentThread().name}") // Launching a coroutine val job = launch { delay(1000) // Non-blocking delay (suspends coroutine) println("Coroutine says hello from: ${Thread.currentThread().name}") } println("Main continues...") job.join() // Wait for the coroutine to finish println("Main ends: ${Thread.currentThread().name}") }  ( 3 min )

    The most useful data structure for leetcode
    Recently I decided to enhance my programming logic so I started making some leetcode problems daily just to exercise, but as always I feel a lot of difficulty doing this logic exercises until youtube recommended this video from a Brazilian tech content creator where he teach how to solve one of the most common exercises from tech interviews using a map. Map is a data structure where can store a value combined with a key, so if you need to access this data later you can use the key instead of interating an entire array to find a value (just like the filter and find methods in javascript). You can simplify the logic with a map instead of using a lot of for loops to make the exercise, being more legible and understandable. When you iterate an array, your code have the complexity of O(n) where n is the size of the array because you have to iterate the entire array, when using a Map, operations such as get and set have a time complexity of O(1) because the Map relies on a hash table internally. This structure allows the engine to compute the exact location of a value based on its key, so it can access or update entries directly without iterating through all keys and values. As a result, the performance of these operations remains constant regardless of the size of the Map, depending only on the key being used rather than the total number of elements stored.  ( 3 min )

    Hello everyone, this weekend! Today, I'll continue to share a practical tutorial on developing a shopping mall application using the Cangjie language. What I'm going to do today is tabbar. Everyone knows that ArkTs has Tabs and TabContent containers, which can achieve the style shown in the above picture and meet the basic usage requirements. However, Cangjie is different. Although it also has these two components, its tabbar parameter only supports the input of images or text, and cannot input components like ArkTs. Therefore, the official tabbar in the Cangjie language has very significant limitations. Let me give you a practical explanation.

    From Fired Accountant to Future Cloud Engineer
    Hi everyone My name is Jabulani (still trying the nickname jay-sys), and this post is the beginning of a story I never thought I’d be telling, the story of how getting fired turned into the best thing that ever happened to me. The Short Version: Former accountant Fired for struggling with ADHD in a rigid work environment Diagnosed late, felt broken for a while Found hope in tech — specifically cloud computing Switched to Linux (Debian) Now teaching myself cloud engineering full-time Studying for LPIC-1, LPIC-2, and cloud certifications Using this blog to stay accountable, document the process, and hopefully inspire someone like me ## Why I’m Doing This I used to think I was just “bad at work.” I couldn’t keep up with long meetings, paperwork, and soul-draining tasks. Turns out, I wasn’t lazy my brain just worked differently. After getting fired, I spiraled. But after some hard reflection (and a lot of YouTube), I discovered cloud computing and something clicked. It felt flexible, creative, logical and possible. I don’t have a computer science degree. I don’t come from tech. But I do have grit, curiosity, and something to prove (mostly to myself) I'll be sharing: 🧪 What I’m learning (Linux, cloud platforms, cert prep) 🧠 Struggles + breakthroughs with ADHD in tech ⚙️ Personal projects, CLI tools I love, lessons from failures 🧰 Resources I actually found useful 🎯 My progress toward becoming job-ready in cloud This blog is my accountability partner, my digital journal, and my way of telling the world: You can start over. Even when it feels like you’ve got nothing figured out. If you’re self-taught, neurodivergent, or just trying to break into tech from a non-traditional background I’d love to hear from you. And if you’re further along the path, feel free to drop tips, encouragement, or even corrections I’m here to learn out loud. Thanks for reading.

    Third individual arrested in NYC crypto torture and kidnapping case
    A third individual, suspected of being connected to the recent kidnapping, torture and attempted extortion of an Italian tourist in New York City, surrendered to law enforcement on May 27. 33-year-old William Duplessie was taken into custody by the New York Police Department (NYPD) and will be charged with “kidnapping and false imprisonment of an associate,” NYPD Commissioner Jessica Tisch said. The incident comes amid a string of kidnappings and ransom attempts targeting crypto investors and their loved ones, prompting additional security measures from investors and industry executives. According to reporting from The New York Times, Duplessie and crypto investor John Woeltz, who was previously arrested by police in connection with the case, both had connections to an NYC-based crypto hed…
    Here’s what happened in crypto today
    Today in crypto, Representative Bryan Steil tells Cointelegraph he wants lawmakers to stop adding non-relevant clauses into crypto bills, Trump Media confirmed a capital raise to buy Bitcoin after initially denying reports it would, and Circle announced its initial public offering on the New York Stock Exchange. Rep. Steil wants restraint on crypto bill additions Republican Representative Bryan Steil told Cointelegraph on May 27 that he wants lawmakers to stop adding what he considers are non-relevant clauses into two key crypto bills, claiming that doing so is slowing the implementation of a regulatory framework for the industry. “Individuals, when they see legislation that’s going to move forward, want to attach non-germane items to any bill that’s going to move through and be signed int…
    Growing BTC reserve requires Congressional legislation — VanEck exec
    Building a permanent US strategic Bitcoin reserve would likely require targeted legislation rather than executive action, according to VanEck’s head of digital assets, Matthew Sigel. Speaking at Bitcoin 2025 in Las Vegas, Sigel said the most viable path forward may involve inserting Bitcoin mining incentives into the congressional budget reconciliation process. According to Sigel, the most effective path to growing a US strategic Bitcoin reserve would be through targeted amendments to congressional budget legislation. These could include tax credits for mining companies that use methane gas and other incentives aimed at encouraging miners to share a portion of their mined BTC with the federal government. He argued that such an approach would allow the reserve to grow organically over time…
    Trump supports bill to buy 1 million BTC — Senator Lummis
    US President Donald Trump supports the BITCOIN Act and has a team of experts in the White House working to roll out landmark digital asset legislation in the coming weeks, according to Wyoming Senator Cynthia Lummis.  Speaking at the Bitcoin 2025 conference in Las Vegas, Nevada, Lummis said she is bringing the BITCOIN ACT to the “attention of the American people and the world,” adding that, “President Trump supports the bill.” In March, Lummis reintroduced the BITCOIN Act — landmark legislation that directs the US government to acquire 1 million Bitcoin (BTC) over five years. The acquisitions would be financed using existing funds within the Federal Reserve System and the Treasury Department.  As Cointelegraph reported, the Trump administration has reiterated the need to use “budget-neutra…
    Selling Bitcoin is like playing in a 'bad house-rate casino' — Adam Back
    Selling Bitcoin is like “playing in a really bad house-rate casino,” according to Adam Back, CEO of Blockstream and one of Bitcoin’s earliest adopters. In a recent interview with Bitcoin financial services firm Unchained, Back said the odds are stacked against traders trying to time the market. Back came to this conclusion in the early days of Bitcoin, he said, when the price “was going up basically exponentially but it [was] extremely volatile.” “So [...] if you see something that’s going up exponentially but with volatility, if you sell it to time the market a bit falling, the odds are against you,” Back said, adding: “The trend line is up and to the right, exponential, and so there’s extremely bad trading odds attached to selling because you’re really hoping that it falls.” Adam Back du…
    Maple Finance, FalconX secure Bitcoin-backed loans from Cantor Fitzgerald — Report
    Wall Street financial firm Cantor Fitzgerald has closed its first Bitcoin lending deal nearly a year after announcing its crypto lending services. According to a May 27 Bloomberg report, Cantor provided Bitcoin-backed loans to FalconX and Maple Finance. FalconX, a digital asset broker, said it secured a facility worth over $100 million as part of a “broader credit framework,” while Maple Finance reportedly closed the first tranche of an agreement with Cantor. The service allows companies holding Bitcoin to borrow funds and use the cryptocurrency as collateral, providing a way to unlock liquidity without selling their BTC holdings. Cantor announced its Bitcoin financing business with an initial capital of $2 billion in July 2024, targeting institutional investors seeking to leverage their B…
    Bitcoin price held up by corporate adoption and ‘inflation hedge’ narratives
    Key takeaways: Institutional investor demand and corporate adoption may push Bitcoin higher despite recession fears. Investors’ belief that the US Federal Reserve will hold rates favors Bitcoin price upside. Stock markets around the world responded positively to the temporary suspension of import tariffs between the United States and the European Union, with the S&P 500 rising 1.5% on May 27. However, concerns over a global economic recession persist, capping Bitcoin’s (BTC) upside, especially since the baseline US import rates have been raised for most regions. Bitcoin remains antifragile and poised to outperform in uncertain times Given the growing investor uncertainty about economic conditions, Bitcoin hovering around the $110,000 level has taken investors by surprise as it consolida…

According to a May 27 announcement, the strategies will include buying undervalued biotech companies, purchasing “distressed Bitcoin claims” like those associated with crypto hacks and bankruptcies, and acquiring bottom tranches of Bitcoin credit vehicles at discounted prices. “ [...] our alpha-generating Bitcoin accumulation strategies are designed to drive sustained outperformance relative to Bitcoin itself, which requires a new valuation framework,” Strive CEO Matt Cole said.

As of March 31, 2025, the BlackRock Strategic Income Opportunities Portfolio held 2,123,592 shares of the company’s iShares Bitcoin Trust (IBIT), valued at $99.4 million, according to filings with the US Securities and Exchange Commission (SEC).

    Bitcoin profit taking lingers, but rally to $115K will liquidate $7B shorts
    Key takeaways: Bitcoin could turn parabolic if prices move above $115,000 to liquidate more than $7 billion in short positions. Onchain indicators enter overheated territory, suggesting prolonged profit-taking from BTC investors. Bitcoin (BTC) showed strength on May 27, briefly tagging $110,700 after a strong US equities market open and the Trump Media and Technology Group’s announcement that it would raise $2.5 billion for a Bitcoin treasury. Bitcoin’s bullish momentum aligns with the favorable US financial conditions, as noted by Ecoinometrics. The macroeconomic-focused Bitcoin newsletter highlighted that the National Financial Conditions Index (NFCI) shows a rapid shift to ultra-loose territory after a tightening phase in February 2025. The NFCI, published by the Federal Reserve Ba…
    93% of all Bitcoin is already mined. Here’s what that means
    How much Bitcoin is left to mine? Bitcoin’s total supply is hardcoded at 21 million BTC, a fixed upper limit that cannot be altered without a consensus-breaking change to the protocol. This finite cap is enforced at the protocol level and is central to Bitcoin’s value proposition as a deflationary asset. As of May 2025, approximately 19.6 million Bitcoin (BTC) have been mined, or about 93.3% of the total supply. That leaves roughly 1.4 million BTC yet to be created, and those remaining coins will be mined very slowly. The reason for this uneven distribution is Bitcoin’s exponential issuance schedule, governed by an event called the halving. When Bitcoin launched in 2009, the block reward was 50 BTC. Every 210,000 blocks — or approximately every fou…
    Ethereum flashes ‘altseason’ signal as ETH price eyes $4.1K
    Key takeaways: Ethereum has reclaimed a key level that preceded 100%+ rallies and triggered past altseasons. Altcoin market cap could surge toward $15 trillion if Bitcoin dominance repeats its post-halving drop. Despite bullish signals, ETH remains fragile, with $123B in supply near cost basis at risk of flipping into a loss. Ethereum’s native token, Ether (ETH), has reclaimed a key technical level that has historically preceded sharp price gains and marked the start of an “altseason” across multiple market cycles in the last five years.

    ZKPs can prove I'm old enough without telling you my age
    Opinion by: Andre Omietanski, General Counsel, and Amal Ibraymi, Legal Counsel at Aztec Labs What if you could prove you're over 18, without revealing your birthday, name, or anything else at all? Zero-knowledge proofs (ZKPs) make this hypothetical a reality and solve one of the key challenges online: verifying age without sacrificing privacy.  The need for better age verification today We're witnessing an uptick in laws being proposed restricting minors' access to social media and the internet, including in Australia, Florida, and China. To protect minors from inappropriate adult content, platform owners and governments often walk a tightrope between inaction and overreach.  For example, the state of Louisiana in the US recently enacted a law meant to block minors from viewing porn.

    What is a cryptocurrency mixer and how does it work?
    Cryptocurrency mixers explained A cryptocurrency mixer is a specialized service designed to increase the privacy and anonymity of blockchain transactions.  Unlike traditional financial transactions, which are private by default, most cryptocurrencies such as Bitcoin (BTC) and Ether (ETH) operate on public blockchains. This means every transaction is permanently recorded and accessible to anyone, making it possible for blockchain analysts or malicious actors to trace the flow of funds between wallets. A crypto mixer’s primary function is to break the link between the sender’s wallet and the recipient’s wallet. It does so by pooling together coins from many users and then redistributing them in a way that makes it difficult to track which coins went …

    Solana may be a memecoin ‘one-trick pony’ — Standard Chartered
    Layer-1 blockchain Solana may be evolving into a “one-trick pony” for memecoin generation and trading, according to a recent Standard Chartered report. According to a May 27 Standard Chartered research report shared with Cointelegraph, Solana “dominates in areas that demand high-volume, low-transaction-cost solutions” due to its design prioritizing fast and cheap transaction confirmation. The report suggested that this has had an unintended consequence: “So far, this has been mostly in memecoin trading, which accounts for the majority of activity on Solana (as measured by ‘GDP’, which is application revenue).” Standard Chartered said the memecoin frenzy served as a stress test for Solana’s scalability but came with drawbacks due to the volatility and speculative nature of such assets.

    Luxembourg flags crypto companies as high risk for money laundering
    Luxembourg classified virtual asset service providers (VASPs) as high-risk entities for money laundering in its 2025 National Risk Assessment (NRA), highlighting concerns over the crypto industry’s exposure to financial crime. According to the report, the inherent risk level of VASPs is deemed “High,” driven by factors including transaction volume, client reach, distribution channels, legal structures and the international scope of operations. The NRA identified VASPs as an emerging risk in its 2020 report after “a detailed assessment of ML inherent risks emerging from virtual assets.” This was followed by a 2022 NRA report deeming “the risks associated with crypto assets and virtual currencies as very high,” because, among other things, they are internet-based and cross-border.

    How central banks are testing blockchain-based monetary policy
    Why are central banks looking at blockchains? Central banks are tiptoeing into the world of blockchain not because it is fashionable but because every part of the money-making machine, from settlement rails to asset custody, is slowly being rewritten as code. The financial industry is already tokenizing money-market funds, Treasurys and even bank deposits. According to the Atlantic Council, 134 jurisdictions are studying or piloting a central bank digital currency (CBDC), up from just 35 in 2020.  Meanwhile, commercial banks have begun to warn that if they cannot move tokenized deposits across public blockchains such as Solana or private ledgers like R3 Corda, they risk being left behind. From a central bank’s vantage point, two questions matter: …

    Christopher Giancarlo, former chairman of the US Commodity Futures Trading Commission (CFTC), has joined Sygnum in an advisory role, where he will help the crypto bank navigate global regulations amid growing institutional interest in digital assets.  Giancarlo’s appointment as senior policy adviser places him alongside 11 other members of Sygnum’s Advisory Council, the company disclosed on May 27. In his role, Giancarlo will advise on regulations and strategic partnerships in both the public and private sectors.  Sygnum is a Swiss banking group dedicated to providing crypto asset services. It’s often called the first digital asset bank, having recently achieved unicorn status following a $58 million funding round.  Giancarlo, who headed the CFTC between 2017 and 2019, said he is joining S…
    Bitcoin long-term holders ‘quietly capitalizing’ with drop to $109K
    Bitcoin markets recently experienced two major liquidation events, causing a cascade of forced selling from over-leveraged traders, but analysts say a distinct pattern has emerged. “Overleveraged short-term traders were flushed out, long-term holders have been quietly capitalizing on the reset,” CryptoQuant analyst Amr Taha said on May 26.  They noted the first flush occurred when Bitcoin (BTC) fell below $111,000, and over $97 million in long positions were liquidated. As its price broke $109,000, another $88 million in longs were wiped out in the second wave. However, as short-term traders faced margin calls and forced selling, long-term holders (LTH) responded very differently and increased their accumulation. This caused the long-term holder realized capitalization to surge past $28 bi…
    Migos Instagram account hacked in apparent blackmail bid on Solana co-founder
    The Instagram account of former US rap trio Migos was hacked in an apparent attempt to blackmail Solana co-founder Raj Gokal. On May 27, Migos’ Instagram account posted at least seven images seen by Cointelegraph, which have since been deleted. Two of the images appeared to depict Gokal holding up his passport and driver’s license, clearly showing the full details of each document. The account’s hacker tagged Gokal in one of the images that apparently showed him with the caption “you should’ve paid the 40 btc,” while another image depicting Gokal said “it was only 40 btc.. should’ve paid.” Another image posted by the account hacker shows what the caption claimed was Gokal’s wife holding up a driver’s license, while a further two images appear to be a dump of private information, including mobile phone numbers and email addresses. The type of photos posted, where a person holds personal identifying documents in clear view of the camera with their face visible, are commonly used by crypto exchanges in Know Your Customer checks. However, it is unknown where the photos seemingly depicting Gokal and his wife originated and how they ended up being used in the apparent blackmail attempt. The Solana Foundation and Gokal were contacted for comment. Gokal had posted to X on May 20 that attackers had “been trying to take control” of his email and social media accounts, warning his followers to be suspicious of any out-of-the-ordinary posts. Attackers have been trying to take control of my email, social media, Google, Apple, etc. this past week.

    Saylor says onchain proof-of-reserves a ‘bad idea’ due to security risks
    Michael Saylor, the executive chair of major Bitcoin-buying firm Strategy, formerly MicroStrategy, says institutions posting onchain proof-of-reserves is a “bad idea” that could pose security risks. “The current, conventional way to publish proof of reserves is an insecure proof of reserves,” Saylor said when asked about institutions adopting the transparency measure at a May 26 event on the sidelines of the Bitcoin 2025 conference in Las Vegas. “It actually dilutes the security of the issuer, the custodians, the exchanges and the investors. It’s not a good idea, it’s a bad idea.” Saylor didn’t answer whether Strategy would publish its proof-of-reserves when asked by Blockware Solutions head analyst Mitchell Askew whether his firm would do so. I asked @saylor if @MicroStrategy has any pla…
    Meta’s AI boss says current AI lacks ‘intelligent behavior’ — Report
    Current artificial intelligence models lack the major traits of human intelligence, Meta’s AI chief has reportedly said, claiming that the firm’s latest model will solve this issue.  Business Insider reported on May 26 that at the AI Action Summit in Paris earlier this year, Meta chief AI scientist Yann LeCun said that “there are four essential characteristics of intelligent behavior that every animal, or relatively smart animal, can do, and certainly humans.”  “Understanding the physical world, having persistent memory, being able to reason and being able to plan complex actions, particularly planning hierarchically,” LeCun said. He said current large language models (LLMs) that power popular AI chatbots have not hit this threshold, and “incorporating these capabilities would require a sh…
    France’s Blockchain Group to buy 590 Bitcoin after bond sale
    The Paris-based crypto company Blockchain Group is adding more Bitcoin to its growing treasury through a 63.3 million euro ($72 million) bond sale. The company hopes to buy another 590 Bitcoin (BTC) with the funds, increasing its total holdings to 1,437 BTC, the Blockchain Group said on May 26. Bitcoin is trading at over $109,00, and at current prices, the Blockchain Group could buy 658 BTC with the total amount it raised, according to CoinGecko. However, the company said only 95% of the proceeds from the issuance will be used to buy Bitcoin; the remainder is marked for “operational expenses and to pay management fees.” Source: Alexandre Laizet Venture capital firm Fulgur Ventures invested the lion’s share for the bond sale, with 55.3 million euros ($62.9 million), while crypto private inv…
    Another suspect to surrender in NYC crypto torture case: Reports
    A second person suspected of being involved in a high-profile crypto kidnapping case in New York City is expected to turn himself in to police, according to several reports. The second man is a Swiss crypto investor who allegedly assisted business partner Joel Woeltz, who is accused of kidnapping Michael Valentino Teofrasto Carturan and torturing him in a Soho apartment in an attempt to pressure him into revealing his crypto wallet phrase, ABC7 New York reported on May 26. A separate NBC report said the Swiss trader —  who is not named — would turn himself over to police within a week. However, FOX5 New York reported that the man may already be in custody, citing conflicting sources. The New York Post reported that the man is the co-founder of a Swiss trading firm.

    Bitlayer secures 31.5% of Bitcoin's hashrate to bring smart contracts to BTC
    Bitlayer’s Bitcoin smart-contract system is being implemented by mining pools behind 31.5% of the network’s hashrate, a development that will help ensure that its system will operate on the Bitcoin blockchain, the company said. According to a May 27 announcement shared with Cointelegraph, Bitlayer’s BitVM implementation will be supported by major Bitcoin (BTC) mining pools including Antpool, F2Pool, and SpiderPool. Antpool CEO Andy Chow said: "Antpool has become the bridge operator for Bitlayer to support Bitcoin innovation and protect miners’ interests.” BitVM (Bitcoin Virtual Machine) is a framework that enables complex smart contracts to be deployed on the Bitcoin blockchain without changing the base protocol. The idea was introduced by Robin Linux in 2023, and allows for the complex co…

    Tattooing Is a Creative Language — Just Like Code
    I’ve always believed tattooing is more than just body art. It’s a language—one that combines structure, emotion, precision, and design. The more I reflect on my work, the more I notice how much tattooing mirrors the process of coding. Both require: Clear communication A strong foundation before layering on complexity Attention to detail Respect for the end user (or in my case, the client) In tattooing, every line matters. Every piece must flow with the body, just like good code flows with logic and user experience. There's room for creativity, but also discipline—just like in dev work. Whether I’m sketching full sleeves or crafting micro-details, I see tattooing as visual problem-solving. My goal is always to translate someone’s story or idea into a lasting, wearable design—something functional, aesthetic, and deeply personal. If you're a developer, designer, or builder of any kind: you're a tattoo artist too in your own way. We all leave marks—some visible, some digital—but all meaningful. Let’s keep creating with intention. — Isaac Bokhoor  ( 3 min )

    Introduction to PostgreSQL
    What is PostgreSQL? PostgreSQL is an advanced, open-source RDBMS that supports both SQL (relational) and JSON (non-relational) querying. It is highly extensible, allowing users to define custom functions, data types, and extensions. History and Evolution PostgreSQL’s origins trace back to 1986 at UC Berkeley as the POSTGRES project. It evolved into PostgreSQL in 1996, adopting SQL standards. Over decades, it has grown into a feature-rich database, with releases like PostgreSQL 17 (2024) introducing enhanced JSON support and performance optimizations. Key Features and Advantages PostgreSQL offers ACID compliance, MVCC (Multiversion Concurrency Control), extensibility, and support for advanced data types (e.g., arrays, JSONB). Its advantages include robust transaction support, a vibrant comm…  ( 6 min )
    The Art of Automation in Modern Engineering
    The Art of Automation in Modern Engineering Designing Systems That Think Without Forgetting to Feel By Nigel Dsouza We used to automate because we were lazy. Now we automate because we must. In a world of hyperscale systems, incident fatigue, and the unrelenting pressure of uptime, automation is no longer a luxury — it’s the nervous system of modern engineering. But here’s the catch: Most automation isn’t beautiful. It’s brittle. It’s soulless. It gets the job done, but no one knows how. Or why. Or what to do when it breaks. Which begs the question: What if automation could be art? Real automation isn’t about writing bash scripts or wiring up webhooks. It’s about designing intent. It’s about: Embedding wisdom into pipelines Anticipating failure Choreographing recovery Or…  ( 4 min )

MCP provides a standard way to link the LLM application you are using with the instructions to the agent on what tools and abilities are available to it and how to use them.

    Your First AI Cloud Project with AWS: Start with Real-Time Data Ingestion
    The Big Picture: Why This Project Matters In the age of AI-driven decisions, retail businesses are sitting on a goldmine of customer interaction data, but most are struggling to use it effectively. Imagine this: A customer browses your store but leaves without buying. You don't know what caught their eye. You don’t know what’s likely to sell tomorrow.

The goal of this project is to build a cloud-native, AI-enhanced retail analytics platform that solves two critical business problems: What do you think we should stock next? → Predict demand using historical data and forecast which products need restocking. What should we recommend? → Use customer behavior to serve personalized product suggestions at run…  ( 9 min )

    Lonely Island RPG
    Whereabouts of the Lonely Island "You weren't chosen. You never were. But this time, you’re not asking." The world turned while you stood still. You tried to be someone. A taxi driver who couldn’t find his way home. A software developer whose code always compiled — but never connected. A dozen roles played, a thousand dreams deferred. You lived in the margins. A quiet shadow in fluorescent cities, drifting from rejection to rejection like an errant file lost in a corrupted sector. But something changed. One night, a map appeared in your terminal — glitching into view between job rejections and broken threads. It bore no coordinates, only a phrase: "The Lonely Island Knows." Now, you are no longer waiting. Across flooded subway tunnels, through whispering forests of abandoned silicon, and past ghost towns built on failed prototypes, you chase a legend whispered only on 2600 baud frequencies: The Lonely Island — the place where misfits rewrite fate. This is no hero’s quest. It’s not about saving the world. It’s about finding where it stopped caring about you. It’s about going off-grid — to write a new code into the system of existence itself. Prepare for cryptic terminals, sentient algorithms, neon storms, and voices from other timelines who almost made it. Your failures were your training. Your rejection is your power. And your destination is unknown... Whereabouts of the Lonely Island™ A solo journey through the memory dumps of fate. Coming soon to a system that forgot you.  ( 3 min )

    The Big Three Cloud Providers Have All Launched AI Copilots for DevOps
    Cloud copilots have officially arrived across the Big Three! 👏 All three major cloud providers—Google Cloud, AWS, and Azure—now offer AI copilots purpose-built for DevOps and Reliability Engineering. Though branded differently, they all share a common goal: shortening Mean Time To Recovery (MTTR) by automatically analyzing observability data, linking it to infrastructure context, and guiding teams through root cause analysis and remediation. It's hardly surprising that LLM-powered assistants have reached the cloud infrastructure space, given how rapidly they're gaining ground across every layer of modern software development. From code completion to testing, AI copilots are becoming indispensable tools for developers and operations teams alike. In this competitive landscape, Google led the charge, Amazon followed suit, and Azure has just joined the party: Status: Well-established market leader Previously: Duet AI Learn more: Gemini for Google Cloud Status: Strong contender in the race Focus: Developer productivity and operations Learn more: Amazon Q Developer Status: Latest addition to the lineup Specialty: Site Reliability Engineering workflows Learn more: Azure SRE Agent While these solutions currently serve as intelligent assistants that support human decision-making, we might be witnessing the early stages of a fundamental shift. In the future, AI copilots could evolve from supporting tools to become the primary interface for incident response and infrastructure management. This evolution raises fascinating questions: How will the role of SREs and DevOps engineers evolve? What new skills will teams need to develop? How will we balance automation with human oversight?

    The Artistry Rack Guide to Creating Masterpieces with Custom Paint by Numbers
    What is a Custom and Personalized Paint by Numbers Kit? Unlike traditional kits that come with pre-selected designs, a custom paint by numbers kit allows you to upload a photo—of a loved one, pet, scenic view, or even a cherished memory—and turn it into a paintable canvas. The kit includes everything you need: A pre-printed numbered canvas based on your image A full set of corresponding acrylic paints Multiple brushes of varying thickness Optional frame or stretching tools for display It's art made personal, and it's transforming how people engage with painting at home. By painting a subject that holds meaning for you, such as a wedding photo or a beloved pet, the experience becomes not just artistic, but deeply personal. It adds sentimental value that no store-bought wall art can match.…  ( 4 min )
    A quick guide to push notifications with expo-notifications and Firebase
    These days I had to implement push notifications, and since I really like the direction Expo is going, I decided to lean more into its ecosystem, so I chose to use expo-notifications to implement the feature. To my surprise, I couldn't find any good guides on how to do it. Expo has a guide on how to set it up through their proprietary services, which I decided not to use to avoid the feeling of being platform-locked. Personally, the biggest benefit of Expo is keeping the manual implementation and management of native code to a minimum, as the longer a project lives, the harder it becomes to keep track of changes in different files for numerous libraries. So we will leverage Expo's strengths using expo-notifications to set up pretty much all the native code and handle push notifications in …  ( 7 min )
    Migrating from WebForms to WebForms Core
    This video teaches you how to migrate from Microsoft's former WebForms to Elanat's WebForms Core technology. This tutorial was done under the CodeBehind framework owned by Elanat. Migrating from traditional WebForms to WebForms Core offers several advantages: Modern Architecture: WebForms Core introduces a revolutionary approach to handling DOM elements directly from the server, eliminating the need for front-end frameworks. Cross-Language Compatibility: Unlike classic WebForms, WebForms Core supports multiple programming languages, including C#, Python, Java, PHP, Ruby, Swift, Elixir, NodeJS, GO, and Rust. Improved Performance: The new architecture reduces server load, eliminates ViewState bloat, and optimizes data transmission, leading to faster page loads. Event-Driven Structure: It supports all HTML events and integrates seamlessly with MVC, MVVM, and MVP development patterns. Efficient Data Handling: Instead of full-page reloads, WebForms Core uses XMLHttpRequest to send small, efficient commands to the client. Enhanced Control Over HTML: Developers gain greater flexibility in managing UI components without the limitations of traditional WebForms.  ( 3 min )

    🧭 Introduction to Web Accessibility (a11y) – where to start?
    Accessibility, often abbreviated as a11y, ensures digital content and functionality are usable by people with disabilities — including visual, auditory, motor, and cognitive impairments. It’s not an optional feature or a stretch goal. In many regions, it’s a legal requirement. Everywhere, it’s a core quality standard. One in five people experience disability. If your app doesn’t support screen readers, keyboard navigation, or high contrast modes — it’s broken for millions. Web accessibility refers to the design and development of websites, tools, and technologies so that people with disabilities can perceive, navigate, interact with, and contribute to the web. Accessibility supports a broad range of user contexts: Visual: blind, low vision, color blindness, Auditory: deaf or hard of hearin…  ( 6 min )

    Leadership
    Definition Leadership is the ability to guide, influence, and inspire others toward achieving common goals. Strong leadership is vital because it: Sets clear vision and direction for the team Motivates and empowers individuals to perform at their best Builds trust, cohesion, and a positive work environment Drives innovation and change in dynamic markets Ensures accountability and effective decision-making Different theories explain how leaders behave and adapt. Key styles include: Autocratic Leader makes decisions unilaterally Fast decisions, clear authority Can stifle creativity and buy-in Democratic Leader involves team in decision-making Builds commitment and diverse ideas May slow down urgent decisions Laissez-Faire Leader provides freedom and resources, minimal direction Encourages autonomy and innovation Risk of role confusion and lack of coordination Transactional Focus on exchanges: rewards for performance Clear structure and expectations Limited to short-term goals and routine tasks Transformational Inspires and motivates through vision and passion Drives change, fosters personal growth Requires strong charisma and emotional intelligence Servant Puts team’s needs first, emphasizes empathy Builds strong relationships and trust May be seen as less assertive in crisis Each style suits different situations. Effective leaders often combine multiple approaches to meet their team’s needs and organizational challenges.  ( 3 min )
    Polymorphic C
    Polymorphism—the ability to write functions whose behavior depends on the type and number of their arguments—is a feature of many modern programming languages. In the C world, this concept is especially relevant to library writers or developers implementing the backend of a complex system: fellow programmers prefer a clean, consistent API over dozens or hundreds of closely related functions that differ only by name and signature. Too often, APIs end up littered with near-identical functions such as: result_type mixdown_integer_and_string(int x, char *y); result_type mixdown_unsigned_integer_and_string(unsigned int x, char *y); result_type mixdown_string_and_float(char *x, float *y); // and so on ... each variant must be remembered and called explicitly, making the interface hard to learn …  ( 8 min )

    Mustiolo: A Python library for creating CLI applications.
    A couple of weeks ago, I started to wonder if it is possible to write a library in Python to create a CLI application that uses only standard packages as dependencies. The idea seems fun, so I've started to build it. command register via decorator, autocomplete, command history, help menu via docstring, Use of typing hints and annotations to retrieve: mandatory/optional parameter parameter type (and check types). Long road to accomplish something more complete, like sub-commands. The 'mustiolo' is the smallest mammal in the world, weighing about 1.2-2.5 grams as an adult. This library aims to be the smallest library for building CLI applications in Python just like a mustiolo is the smallest mammal. from mustiolo.cli import CLI cli = CLI() @cli.command() def greet(name: str): """Greet a user by name.""" print(f"Hello {name}!") @cli.command() def add(a: int, b: int): """Add two numbers and print the result.""" print(f"The result is: {a + b}") if __name__ == "__main__": cli.run() This example allows to have > ? greet Greet a user by name. add Add two numbers and print the result. > ? add Usage add Add two numbers and print the result. add A B Parameters: A Type INTEGER [required] B Type INTEGER [required] > exit If you're interested please visit Mustilo repository on GitHub.  ( 3 min )
    Sharding Demystified

    Concurrent Testing in Go: Taming My Netcat Broadcaster and Shared State
    Welcome back to our series on taming Go unit test timeouts! In Part 1, we tackled the frustrating "panic: test timed out" error, focusing on how SetReadDeadline and channels helped us fix hanging client connections. Now, we're diving into a more complex problem: concurrent testing, specifically how to reliably test the "broadcaster" part of my Netcat-like chat application and manage shared information. Testing code that runs in parallel can introduce tricky problems like race conditions (where different parts of your code try to change the same thing at the same time) and subtle timing issues. My broadcaster tests were a prime example of this challenge. In my chat application, the "broadcaster" is like the central hub. Its job is to take messages and send them out to all connected clients.…  ( 7 min )
    PostmarkGBA: A working GBA emulator running through Postmark
    This is a submission for the Postmark Challenge: Inbox Innovators. PostmarkGBA is a working GameBoy Advanced emulator, receiving inputs through Postmark Inbound Stream to emulate game inputs and create new emails through Postmark Transactional Stream. The result is much like "Twitch Chat Plays", but playable in your inbox! To get started, simply send an empty mail to postmarkgba@partyrens.nl to get started! You'll get a new mail with a screenshot of the current game state, and an explanation on how to control. Everybody's playing on the same GameBoy, so collaboration is key! Why not use this thread to see if we can reach the first gym before the end of the challenge? Source code is available on GitHub. Please note that the current build is heavily reliant on a combination of Raspian OS and RetroPie. When I read about the challenge, I immediately wanted to make some kind of game. The first idea was some kind of AI powered Cluedo-like murder mystery, but it felt like a game everybody already knew was more fun. Hence, the GBA emulator. Getting a recent version of Nest.JS running on RetroPie was a real pain, as well as taking screenshots of a display when in a systemd process. After realizing RetroArch also has native screenshot hotkeys, it just became a job of emulating keyboard inputs without worrying about screenshot libraries. Postmark intergration on the other hand, was done without a problem. It's not really a team member, but I want to give special thanks to Claude 3.5 for having my back through the long night of trying all screenshot libraries in existence ;). Also my friends for the fun and drinks during development and testing.  ( 4 min )
    A Deep Dive into Go's select
    In Go, select is a control structure used to handle multiple channel operations. It is very powerful and is often used in concurrent programming, especially when you need to select an available operation from multiple channels. Below is a detailed explanation of how to use select and some common scenarios: select { case <-ch1: // Code executed when ch1 is readable case ch2 <- value: // Code executed when ch2 is writable case result := <-ch3: // Read data from ch3 and assign to result default: // Code executed if no case is ready } The working principle of select is similar to switch, but it is specifically designed for channel operations. It blocks and waits until one of the cases' channel operations can be executed. If multiple cases are ready at the same time, select wil…  ( 5 min )

    Making AI Less of a Black Box: The Basics of Explainable AI
    You know that feeling when your GPS suddenly tells you to take a weird detour, and you're sitting there like "why though?" That's basically how we feel about AI most of the time. It makes decisions, gives recommendations, or flags your email as spam, but good luck getting a straight answer about why. Enter Explainable AI (XAI) – basically the movement to make AI systems less mysterious and more... well, explainable. Think about it: if an AI system is helping doctors diagnose diseases, approving loans, or deciding who gets hired, shouldn't we understand how it's making those calls? It's not just about curiosity – it's about trust, fairness, and catching mistakes before they matter. The problem is that modern AI, especially deep learning, is incredibly complex.

    Social Media Widgets and Privacy
    With the decline of X/Twitter and the proliferation of other social platforms with more open APIs, I've noticed many developers sharing social widgets and components to embed in blog posts. Mainly to display conversation and reactions. Most of the social media widgets I've come across share a common issue that, in my opinion, should be prioritized: privacy and security, especially related to the media used in these components. I will go one step further and say this: If you're creating your own comments or likes section based on platforms like Mastodon or Bluesky, reconsider your strategy, and avoid directly linking to avatars hosted on external social platforms. Instead, route them through your backend server. This may sound like a "tinfoil hat" moment, but it's an important consideratio…  ( 5 min )
    🚀 Create a Global phpdev Command to Launch Laravel + Vite Simultaneously
    👋 The Real-Life Developer Struggle A few weeks ago, I sat down to work on a client’s Laravel project. Like always, I opened my terminal, typed php artisan serve, then in another tab, ran npm run dev. 🤦‍♂️ That’s fine for once or twice — but if you’re hopping between multiple Laravel projects daily, this gets really repetitive. I thought to myself: "Why not create a custom terminal command that launches both servers at once?" So I built a global phpdev command. Now I just type: phpdev ...and both my backend and frontend fire up instantly. Here’s how you can set it up too — step-by-step and OS-friendly. Create a script that runs php artisan serve and npm run dev in parallel Make it globally accessible as a phpdev command Ensure cross-platform compatibility (Linux, macOS, Windows) Laravel installed (php artisan must work) Node.js installed (npm run dev must work) A terminal environment (e.g., Terminal, Git Bash, WSL, or Command Prompt) mkdir -p ~/.local/bin phpdev script: nano ~/.local/bin/phpdev Paste this inside: #!/bin/bash php artisan serve & npm run dev & runs the Laravel server in the background so both commands can run concurrently. chmod +x ~/.local/bin/phpdev In your ~/.bashrc, ~/.zshrc, or shell config, add: export PATH="$HOME/.local/bin:$PATH" Then reload your terminal: source ~/.bashrc # or source ~/.zshrc Create a directory for scripts if not present: mkdir -p ~/.local/bin nano ~/.local/bin/phpdev Paste the same script: #!/bin/bash php artisan serve & npm run dev chmod +x ~/.local/bin/phpdev In ~/.bashrc (or ~/.bash_profile), add: export PATH="$HOME/.local/bin:$PATH" Then: source ~/.bashrc ✅ Now you can type phpdev in any Laravel project folder using Git Bash or WSL. Navigate to any Laravel project: cd ~/Projects/my-laravel-app phpdev Both servers should start. No more tab switching or manual steps!  ( 4 min )
    Wade’s Law of Need (aka: "Where’s that backup now?")
    "The need for something is inversely proportional to its availability." Wade's Law of Need is the idea that the more urgently you need something, the less likely it is to be available. It’s a familiar pain point in IT—and once you see it, you start noticing it everywhere. The law came out of years in operations and site reliability work, where you develop a sixth sense for when things will go wrong. The law has been summed up in countless moments like: Backups: “If you don’t have a backup, you’re going to need one. If you do have backups, you probably won’t need them.” Upgrade rollbacks: “If you don’t have a backout plan, the upgrade is all but guaranteed to fail.

    🧠 Perplexity vs. ChatGPT: Why Comparing Them Is Like Mixing Up a Search Engine and a Therapist 🤯 Turns out they’re not even the same species! 🧐 In the world of AI tools... I used to think that too… until I dove deeper and realized: ❗They are designed with completely different philosophies and serve fundamentally different purposes. 🔍 They’re Not the Same Thing at All! So comparing ChatGPT and Perplexity is not apples to apples. 📰 Perplexity = Real-Time Search Genius ✅ Always fetches current data ⚠️ In contrast, ChatGPT (no web) relies on model memory — which may be outdated, especially for 2024–2025. 🎨 ChatGPT = Creative, Interactive Superbrain 🧠 Remembers context (Pro/team mode) Perplexity? It forgets what you just said. It’s not here to vibe with you. 😅 💸 Why Doesn’t ChatGPT Fetch Real-Time Info Like Perplexity? 💰 ChatGPT has millions of users — real-time search would be insanely expensive ✅ So Which One Do I Use? ✨ Final Thoughts Use them right — and AI becomes your superpower. — written with ChatGPT ❤️ Jennifer Chen  ( 4 min )
    third phase
    In this phase, we shift from preparing data to putting it to work with AI. Our goal is to predict product demand based on historical sales using Amazon Bedrock, and do it the way real-world production systems would. Objective We'll build a nightly forecasting workflow that: Reads pre-aggregated sales data from S3 Gold Zone (forecast_ready) Sends that data to Amazon Bedrock for demand forecasting Updates the forecasted_demand field in our DynamoDB inventory table Runs entirely on Amazon EC2, triggered automatically every 24 hours Now, the question here is why we choose EC2 to run the forecasting job? Because in real-world ML systems, long-running batch jobs like forecasting are often too heavy for Lambda, may require more memory, longer runtimes, or even GPU-based instances. Using EC2 gives…  ( 6 min )

    Dockerizing Spring Boot application with database and Vite frontend
    In this article I will show you how you can make a docker compose configuration for a fullstack application with Spring Boot API as backend, a vite frontend application and Postgres as database. We'll also setup a docker compose configuration for development. We will create a docker compose consisting of 3 services: A backend service with Spring Boot (starter web) A frontend service with a Vite project (anything that supports npm run build and produces a dist folder will work) A database, we will use Postgres, but you can also use the database you prefer We'll also create a development docker compose which only contains a database service. As usual the entire project is available at my github. I assume that the project is a monorepo with the following directory structure: root/ ├─ backend/…  ( 10 min )
    I built a WhatsApp Web UI Clone
    🚀 Just Finished Building a WhatsApp UI Clone (Chats section) — Built with React & Dynamic Mock APIs! Over the past few weeks, I’ve been working on a detailed frontend clone of WhatsApp Web — built entirely using React, Tailwind, and mocked API services. My goal was to recreate the real chat experience without storing any static UI data. Every message, contact, and interaction is dynamically fetched — making the app easily integratable with backends like Firebase, Supabase, or a custom Node API. Here are some highlights I’m proud of: 🔧 Built for scalability — the frontend is backend-agnostic and ready for real-time integrations Would love your feedback or suggestions! 🙌 https://github.com/SoorajSNBlaze333/whatsapp-react-clone https://chat-react-clone.vercel.app  ( 3 min )
    Early Return vs. Classic If-Else: A Universal Pattern for Writing Cleaner Code
    Writing conditional logic is something every developer does—no matter the language. But how you structure those conditions affects how readable, testable, and maintainable your code becomes. In this post, we’ll look at two common approaches: Early return (also called guard clause) Classic if...else nesting These patterns are relevant across any language—from PHP and JavaScript to Python, Go, or Java. What Is Early Return or Guard Clause? Early return means exiting a function as soon as a certain condition is met—usually to handle an edge case or invalid input. A guard clause is a specific use of early return at the top of the function, to prevent deeper logic from running if key conditions aren’t met. This avoids unnecessary nesting and keeps your core logic flat and easy to follow. if...e…  ( 4 min )
    Apple Ordered to Allow Crypto Payments & NFT Links in iOS Apps After Court Ruling
    In a landmark legal decision, Apple has been ordered to allow external payment options, including crypto payments and NFT links, on iOS. The April 30 ruling marks a major shift in Apple’s long-standing “walled garden” payment policies. “Apple willfully violated this Court’s 2021 Injunction.” Key Takeaways: Developers can now link to external NFT marketplaces and crypto wallets. Apple cannot charge a 30% fee for off-app purchases. No tracking, auditing, or approval required from Apple for external transactions. Developers do not need special entitlements to use crypto-based payments. “This is hugely bullish for mobile crypto games and NFT apps.” Web3 Analyst Following the ruling, Apple updated its policies. Though not loud about it, the change is clear and binding: External links to NFT col…  ( 4 min )
    Setting Up Row-Level Security in Supabase User and Admin
    Row-Level Security (RLS) in Supabase is a powerful feature that allows you to control access to your database tables at the row level, ensuring users can only access or modify data they’re authorized to.

    Static Site Generation (SSG) vs Server-Side Rendering (SSR) in Next.js: A Deep Dive
    As modern web applications demand high performance, excellent SEO, and real-time interactivity, Next.js emerges as a full-stack React framework that empowers developers to choose the right rendering strategy for each page. Two of its core rendering modes—Static Site Generation (SSG) and Server-Side Rendering (SSR)—offer distinct advantages depending on the application's requirements. In this advanced guide, we’ll dissect SSG and SSR in Next.js with technical explanations, use cases, code examples, performance insights, and a decision framework. SSG pre-renders pages at build time, generating static HTML, JSON payloads, and assets that can be deployed to a CDN for ultra-fast global delivery. How it Works: The getStaticProps() function is executed during the build process. For dynamic routes…  ( 5 min )
    Extreme Makeover: Model Driven App edition
    If you've ever delivered a Model-Driven App in Microsoft Power Platform, chances are you've heard this before: "It looks too plain," or "Can we customize the layout more?" While it's true that Model-Driven Apps follow a consistent, structured UI that prioritizes functionality and data integrity, this often leads to a perception that the interface is rigid or uninspired. But here's the good news: while you can’t redesign the entire layout from scratch, you can dramatically enhance the look, feel, and usability of your apps—often without writing a single line of code. With the right configuration choices, modern theming tools, and UX-conscious design patterns, you can deliver applications that are not only effective but also visually appealing and intuitive.

    OG Star Wars Battlefront devs were asked to make Battlefront 3 in just one year, but Pandemic couldn't hit LucasArts' timeline
    TL;DR: After nailing Star Wars Battlefront I and II in one‐year sprints on PS2/Xbox, Pandemic Studios quietly kicked off Battlefront 3…only to hit a brick wall when LucasArts demanded another one‐year turnaround on unfamiliar PS3/X360 hardware. Negotiations stalled, Pandemic’s ambitious space-to-ground combat ideas never left the hangar, and LucasArts shifted the project to Free Radical Design—who also scrapped theirs at 95% completion. Pandemic’s team says they needed “a good two years” to learn the new consoles and build the next-gen experience they envisioned. With Lucasfilm chasing movie marketing windows and unwilling to extend the dev cycle, Battlefront 3 never got the runway it needed—and a truly “next-gen” Battlefront remains the one that got away.  ( 3 min )

    What Is a Case Class in Scala and Why Is It Useful?
    In the world of Scala programming, case classes hold a unique and powerful position, offering functionalities that make them invaluable for developers. Whether you're new to Scala or looking to deepen your understanding, this guide will explore what case classes are and why they are essential in the Scala ecosystem. A case class in Scala is a special type of class that provides additional functionality compared to a regular class. It is defined with the case keyword, followed by the class keyword. Case classes are primarily used for modeling immutable data and come with several pre-defined methods that make them convenient to use. Immutable by Default: Case classes automatically come with val parameters, which makes their properties immutable unless explicitly defined with var. Automatic…  ( 4 min )

    Shrimp Task Manager Research Mode Is Live: Equipping AI with Real Technical Research Capabilities
    From day one, the goal of Shrimp has never been just to delegate or break down tasks to an AI assistant, but to develop an assistant that possesses true upstream and downstream thinking—just like an engineer. However, during development, I quickly realized something: before most engineering tasks even begin, what’s truly needed isn’t “execution” — it’s “research.” That’s why in this update, I introduced the brand-new Research Mode. This article will walk you through its design rationale, practical workflow, and a full experiment I conducted using it.

    The Subtle Trap of ISO Date Strings in JavaScript
    If you’re building any kind of real application, sooner or later you’ll be wrangling dates and times. And the moment your users live in different time zones, things get… interesting. I’ve hit this wall dozens of times — each encounter requiring a quick mental reset, a bit of digging, and a careful rethink of how to handle it all correctly. There’s a fantastic (and slightly terrifying) post on the topic — Falsehoods Programmers Believe About Time — that’s absolutely worth a read. But today, I want to zero in on one specific gotcha: how JavaScript parses ISO date strings, and why new Date(str) and parseISO(str) from date-fns might not behave the way you expect. In the project I was reviewing, dates were stored in ISO 8601 format—but in three different ways: Full datetime with a trailing Z (e…  ( 5 min )
    Alucinações do IA: Como corrigir falhas em textos produzidos com ferramentas de IA?
    Imagine pedir uma informação para uma ferramenta de inteligência artificial e ela responder com confiança… só que está completamente errada. Não por má intenção, mas porque "alucinou". Sim, alucinações não são exclusividade do cérebro humano, o termo também é usado para descrever respostas inventadas por sistemas de IA generativa como ChatGPT, Gemini ou Bard. Mas o que isso significa? O que são “alucinações” em IA? As “alucinações” mais comuns são o uso de citações que nunca existiram; de dados estatísticos sem fonte confiável; de títulos de livros atribuídos a autores errados; de fatos plausíveis, mas sem qualquer base real. “Esses erros acontecem porque a IA não entende o que está dizendo, ela apenas prevê qual palavra tem mais chance de vir a seguir com base em dados anteriores”, explica a editora-chefe da Atena Editora, Antonella Carvalho de Oliveira. Por que a IA “alucina”? Por isso eles não sabem identificar alguns erros ou verificar informações mais subjetivas ou complexas, principalmente em áreas mais sensíveis como pesquisa acadêmica, medicina, direito ou jornalismo, e isso é um risco grave. Dicas para corrigir (ou evitar) alucinações da IA?: Sempre revise manualmente o conteúdo gerado, a IA é um assistente, não um autor final; Use fontes confiáveis para checagem, como dados oficiais, artigos científicos ou veículos jornalísticos de referência; Evite usar IA para citar autores, livros e dados exatos sem conferência; Use ferramentas com acesso a dados atualizados, quando disponíveis, ou peça que ela cite as fonte e verifique-as; Se possível, combine IA com supervisão especializada, principalmente em áreas técnicas. A responsabilidade ainda é humana “Combinando inteligência artificial com revisão humana, conseguimos um conteúdo mais ágil e, ao mesmo tempo, responsável”, alerta Antonella Carvalho de Oliveira.  ( 4 min )

    Hey devs, But every time, I'd end up writing the same boilerplate: set up Express, add auth, handle errors, deploy somewhere, configure rate limiting... you know the drill. I was using Beeceptor for mocking APIs during development (great tool btw), but I kept thinking "what if this could actually run real logic?" Like, what if I could just drag some components together and have a production API ready in minutes?

    ML in 2025: Which Platform Wins — SageMaker or Azure ML? ⚔️
    If you’re building or scaling ML projects in 2025, chances are you’ve already bumped into the same question we had: Both platforms offer powerful tools, automation features, and enterprise-level support. But they also come with key differences, in pricing models, ease of use, ecosystem fit, and even how they handle MLOps workflows. We made a side-by-side comparison in video form to make the choice easier. Here’s what we cover: 🧠 Ease of use – How beginner-friendly is each platform, and what’s the learning curve like? 🔌 Integrations – How well do they plug into their respective cloud ecosystems (and open-source tools)? 🚀 Performance & scaling – How do they handle large models, training pipelines, and distributed workloads? 💵 Pricing flexibility – Which one gives you more control over costs? 🔐 Security & compliance – Important if you're working in regulated industries like healthcare or finance. Whether you're a solo dev experimenting with models, or working on production-level ML pipelines with a team, these are the trade-offs worth understanding. Watch the full comparison here, it's quick, straight to the point, and made for engineers trying to make the best decision for their stack in 2025. And if you're already using one of these platforms, we’d love to hear from you: What made you choose it, and what’s your experience been like so far?  ( 3 min )

    Why Every Automation Needs Webhooks — And How to Use Them in n8n
    What is WebHook? A Webhook is a way for one system to automatically send data to another system when a specific event happens in real time. Think of it like a messenger that delivers a package(data) the moment something happens: A customer places an order. A new form submission is made. A payment is confirmed. Unlike APIs, where we have to ask for data, with Webhooks the data comes to you when it is ready. Webhooks power countless real-world automations and integrations. Here’s an overview of where they’re incredibly useful: 1. Notifications & Alerts New customer order → Trigger an instant Slack or WhatsApp notification. Failed payment → Instantly notify your support team. New contact form submission → Send an email to your inbox or CRM. 2. Data Collection & CRM Updates Form sub…  ( 4 min )

    System Revamp: Stepping Into System Design
    Week 3: A Shift in Perspective Quick Snapshot Learned from Gaurav Sen's system design series Started redesigning my Vimist POS + Inventory system Focus: consistency, transactional integrity, scalability Tech: Django, MySQL, Docker, REST APIs, RBAC LLD in progress, HLD shaping up Two weeks ago, I started blogging. I had no clear direction — just a deep desire to share. That led to my first post: I Almost Didn’t Write This. By week two, I had dived into Docker and system design, writing about scaling, security, and why DevSecOps matters. After bingeing Gaurav Sen's system design breakdowns (Tinder, WhatsApp, Instagram), I saw things differently. It made me look at my own project — Vimist, a POS and Inventory app — and realize: It could be better. So I paused building... and started redesigning. Inventory management Purchases (what, where, who, how paid) Sales (to whom, by whom, payment method) Credit tracking w/ limits & repayments Notifications: low stock, overdue payments Payment types: cash, mobile money, credit Business branding: themes, logos, company details Consistency is a must — money’s involved. That left me debating between: Availability Partition tolerance Still undecided. Any thoughts?

    Searching for a new Keywordkönig
    The German ad agency search platform AgenturTipp has launched it's yearly SEO contest – and this year's keyword to rank for is "Keywordkönig" (German for keyword king). The goal: get the highest possible ranking for this keyword within 4 weeks. Here's how Agentur ID is doing it. For our entry to the Keywordkönig contest, we rely on some SEO essentials, as well as trying out how our headless CMS fares with search engines. High quality content, written by professional copywriters Some AI content to enhance user experience (e.g. videos) Interactive elements to encourage dwell time Backlinks from reputable PR websites and partners Mentions on Social Media, LinkedIn, Medium, DEV, ... Subdomain with the keyword in the URL Structured Data (JSON, schema.org) Rather than spamming the web with yet another AI generated website, we believe that real content, written by real people, will be the way to go for SEO and GEO alike. Our main goal is to thoroughly test our headless CMS. It's a custom system based on react.

    🚀 How I Built My First Python Automation Script (And You Can Too!) Hey devs! 👋
    Hey devs! 👋 I've recently started diving into Python automation, and I wanted to share my experience building my very first script. Whether you're new to Python or just looking for a fun weekend project, this one’s for you! 🛠️ The Idea 📦 Tech Stack -Python 3.10 -os and shutil modules -Runs on any OS (tested on Windows and Linux) 🧠 What I Learned Using shutil.move() to transfer files Writing clean and modular code Running scripts on a schedule with Task Scheduler / Cron Jobs 💡 Code Snippet import os import shutil DOWNLOADS = "/home/user/Downloads" DESTINATIONS = { "Images": [".png", ".jpg", ".jpeg", ".gif"], "Docs": [".pdf", ".docx", ".txt"], "Videos": [".mp4", ".mov"], } for filename in os.listdir(DOWNLOADS): file_path = os.path.join(DOWNLOADS, filename) if os.path.isfile(file_path): for folder, extensions in DESTINATIONS.items(): if filename.lower().endswith(tuple(extensions)): target_folder = os.path.join(DOWNLOADS, folder) os.makedirs(target_folder, exist_ok=True) shutil.move(file_path, os.path.join(target_folder, filename)) print(f"Moved {filename} to {folder}") break 🚧 What's Next? ✨ Final Thoughts Let me know what you're working on in the comments. 💬 Happy coding! 🐍💻  ( 3 min )
    Fixing “502 Bad Gateway” with Gunicorn and Nginx on Ubuntu
    When deploying a Django (or any Python) app using Gunicorn behind Nginx, you might encounter a 502 Bad Gateway error. This article walks you through resolving it, especially if the root cause is: PermissionError: [Errno 13] Permission denied: '/path/to/app.sock' This error occurs when Gunicorn lacks permission to create or connect to the Unix socket file specified in your systemd service file. This results in: Gunicorn crashing Nginx failing to connect to the backend A 502 Bad Gateway error in the browser Fix Socket File Permissions Ensure the user running Gunicorn (e.g., www-data, ubuntu, or a custom deployment user like resquser) has the right permissions to access and create the socket file.

    Chat-First Product Management: Keep Your Startup on Track Inside the IDE
    TL;DR — With one plain‑text rules file your AI coding assistant can walk you from half‑baked idea → Opportunity Brief → MVP Scope → PRD without ever leaving your editor. That means less context‑switching, tighter feedback loops, and a paper trail of Markdown artefacts that live in Git. Speed is a feature for startups, but sprinting often leaves product‑management basics—problem discovery, hypothesis validation, structured scoping—stuck in Notion graveyards. When the documentation layer is detached from the development surface, it always slips. Research on "docs‑as‑code" shows integrating docs with source control can slash onboarding time by 50 % (GitBook — Docs as Code). Yet most IDE extensions still centre purely on code generation.

    Data Quest (0) Introduction
    Data Quest A physicist’s road to “perfect prediction” with ChatGPT as co-pilot I was a physicist who grew up loving Einstein, Feynman, and Erdős. Today I write code in the semiconductor world and keep asking: “Can pure data give us a model that never fails?” I don’t know the answer—but I want to find out, and I’ll log every step here. Year / phase What happened (one-liner) Uni → Grad Switched from Mechanical Eng. to Physics because petawatt lasers sounded cool. PhD days Fought with vacuum pumps, wrote my thesis, survived. First job Built machine-vision & optics for an automation start-up—deadlines every day. Today Work in semiconductors, play with data after hours, dream of a “grand unified model” in data science. data science? Feels useful for almost any problem, let me mix math, code, and real-world impact, and—most of all—my gut says it’s the next big playground. Build a model that can: Predict the future from past data only. Test any new idea without extra experiments. Crazy? Maybe. Exciting? Absolutely. Bite-size experiments with Python, Bayesian tricks, and simulations. Notes on wins, fails, and “aha” moments. Chats with ChatGPT—proving how a non-expert plus an AI buddy can reach pro-level results. Drop ideas, criticism, or questions in the comments. Fork the code, improve it, and open a PR. Tell me when I’m wrong—I’ll thank you in the next post. Thanks for stopping by.

    Looking at c#'s Task>
    On the surface, Task> looks harmless — you're just asynchronously returning a list of things. But under the hood, there's a mismatch between what the caller sees and what the code actually does. Let’s unpack it. IEnumerable is Lazy by Design The IEnumerable interface represents a deferred execution model. It doesn’t hold data — it describes a computation that yields data when enumerated. IEnumerable GetNumbers() Here, GetNumbers() doesn’t do anything until the caller starts iterating. It’s not a collection — it’s a generator. Task> Suggests Lazy + Async — But It’s Not Let’s say you write: public async Task> GetUsersAsync() You're returning a fully materialized list, but your method signature doesn’t say that.

    Beyond the Listing: How Exchanges Support Tokens Post-Launch
    In the cryptocurrency industry, listing a token on a centralized exchange (CEX) is often seen as a milestone. While this event represents significant validation, it is not the endpoint — it’s the beginning of a much more strategic phase. This article analyzes how leading exchanges — OKX, Gate.io, MEXC, Bybit, and WhiteBIT — approach post-listing support and project enablement from a product and developer’s standpoint. For token teams, understanding these mechanisms is essential for driving adoption, maintaining engagement, and supporting healthy trading activity after launch. Each exchange applies different criteria and processes to onboard new projects. Some are community-driven, while others emphasize legal rigor and product maturity.

    👇Primitive and Non-Primitive Data Types
    ✍🏻 Primitive and Non-Primitive Data Types in JavaScript Hello everyone 👋 I’m Himanay Khajuria, a Frontend Developer at SITA.dev, and today I’m going to share something really helpful for anyone who is new to JavaScript ➵ understanding Primitive and Non-Primitive Data Types. Whether you're just starting out or trying to revise your basics, this blog will help you understand these two important concepts in a very simple way with real-life examples. Let's get started! 🏁 Before we dive into primitive and non-primitive, let's understand what a data type is. 👉 In simple words, data types tell JavaScript what kind of value a variable is holding. Just like we know whether something is a number (like 5) or a word (like “hello”), JavaScript also needs to know what type of data you’re using …  ( 4 min )
    What I Learned About Post-Listing Support from Major Exchanges
    Getting listed on an exchange used to feel like crossing the finish line — but today, it’s only the beginning. After reading The Post-Listing Playbook by Tyler McKnight , I realized that post-listing support might just be the most underestimated phase in a token’s lifecycle. In this post, I’ll summarize what I learned about how top exchanges — Gate.io, OKX, MEXC, Bybit, and WhiteBIT — handle the post-listing phase, and why it matters more than ever. 🧠 Listing ≠ Winning 🔍 Exchange Breakdown 🌀 Gate.io 🧠 OKX 📢 MEXC 🔍 WhiteBIT 📊 Bybit 🌍 Regional KOLs Matter 🎯“Getting listed is just a checkpoint — not the final lap.” Whether your token survives — or thrives — depends on what happens after it hits the exchange. Post-listing support isn’t just “nice to have.” In 2025’s fast-moving crypto landscape, it’s mission critical. So before you list, don’t just ask where your token will land. Ask: What happens after we do?  ( 4 min )
    A Practical Guide to Debugging AI-Built Applications
    Your AI-generated app was working perfectly yesterday. Today, it's throwing errors, displaying blank pages, or worse - silently failing without any indication of what went wrong. This scenario plays out thousands of times every day across AI development platforms. The app generation part works brilliantly, but when things break, most users are left stranded. Unlike traditional development where you have full access to logs, database queries, and debugging tools, AI platforms often leave you guessing about what's happening under the hood. If you've already done some basic testing (we covered practical testing strategies in our guide to identifying production issues), you might have found problems but still struggle to understand why they're happening or how to fix them systematically.

    JavaScript-less Mobile Menu with Tailwind
    I've recently been working on a simple static website. One of the goals of the project was to challenge myself to improve my knowledge of CSS and Tailwind. I wanted to see how much I can do without a line of JavaScript. I explored different JavaScript-less options for mobile navigation menus, and the checkbox hack caught my attention. It's simple, and it can teach you a thing or two about how to think outside of the box when it comes to your stylesheets. It can be made accessible with careful attention to ARIA attributes and focus management, though some advanced accessibility features (which are typically JavaScript-reliant) have limitations as discussed later. And here's a fun fact: you can use this pattern to toggle the visibility of anything on your page! So here we are. Here's a JavaS…  ( 8 min )

    The Singleton Design Pattern
    Have you ever been in a house with just one remote control for the TV? No matter who wants to change the channel or adjust the volume, everyone has to use that one single remote. That’s exactly the idea behind the Singleton Design Pattern. Let’s explore this concept in the simplest way possible. The Singleton pattern makes sure that a class has only one instance, and it provides a global way to access it. Think of it like that single remote control in your living room — there's only one, and everyone shares it. Imagine you have a house with multiple family members. Instead of giving each person a different remote (which could get chaotic), you keep just one that everyone uses. Why? Because having one remote: Saves money (no need for 5 remotes), Keeps things in sync (everyone controls the s…  ( 4 min )

    Day I Found My Second Brain💡 (NotebookLM)
    It was a regular Tuesday. You know the kind — too many tabs open, research papers half-read, sticky notes scattered across my desk, and a half-done doc staring at me. I was prepping for a side project on LLMs and drafting a tech blog. But I was stuck. Then Google whispered: NotebookLM. I had seen the name before, but this time I clicked. An AI notebook that "learns" from your content? Sounds like a dream. Five minutes in, I realized it was real. I uploaded: A PDF whitepaper My messy notes A rough Google Doc outline Then I asked: “Summarize the key points.” It delivered. Clean. Structured. Cited. NotebookLM wasn’t summarizing. It was synthesizing. Helping me think. Helping me build. If you're someone who: Turns messy research into clean decks Writes docs, posts, or reports Juggles content from multiple sources Then NotebookLM is like having a second brain. I asked it to write an intro for a talk. It nailed my tone. I asked for a slide flow. It outlined better than my draft.

    The Kind of Leadership That Does Not Need to Speak Loudly
    What does leadership look like in a world that never stops talking? We are surrounded by people competing for visibility. In meetings, on social feeds, in public discourse. Volume and certainty have become currency. But every now and then, someone appears who commands attention by doing the opposite. This piece reflects on one such moment. The appearance of Pope Leo XIV. Not as a religious event, but as a cultural one. A moment when silence said more than slogans. When presence outweighed performance.

    OG Star Wars Battlefront devs were asked to make Battlefront 3 in just one year, but Pandemic couldn't hit LucasArts' timeline
    Pandemic Studios actually kicked off its own Star Wars Battlefront 3 right after Battlefront II, dreaming up seamless space-to-ground battles and next-gen tweaks for PS3/Xbox 360 – but LucasArts only gave them the same one-year window as the previous games. Between new hardware headaches and Lucasfilm’s marketing deadlines (Revenge of the Sith tie-ins, anyone?), the studio couldn’t nail a realistic timeline, and talks fell apart before they’d even built much more than a prototype. Eventually LucasArts handed the series to Free Radical Design, whose version famously made it to about 95% before being canned too, and Pandemic shuttered in 2009. Decades later, EA’s 2017 Battlefront II still thrives, but a true Battlefront 3 remains as elusive as the Death Star plans.  ( 3 min )

    Star Wars Battlefront 2 devs want to ‘get the band back together' to make Battlefront 3
    Turns out the Battlefront 2 crew is itching for a reunion. Developer Mats Helge Holm revealed that he—and a bunch of other ex-DICE devs—would love to “get the band back together” for a Battlefront 3, especially now that the 2017 shooter has enjoyed a fresh wave of popularity thanks to Reddit and TikTok communities. EA officially wrapped support in 2020, but fan enthusiasm is still going strong. You might remember Battlefront 2’s rocky launch, when aggressive microtransactions locked heroes (like Darth Vader) behind roughly 40 hours of grind. EA eventually scrapped the system after massive backlash (Disney even got involved), and went on to drip out new heroes for free. Between that U-turn and the game’s killer graphics and gameplay, fans are now more hyped than ever for what a new sequel could bring.  ( 3 min )
    Warhammer 40,000 Maker Games Workshop Is Doing So Well It's Giving $27 Million to Its Staff
    Warhammer 40,000’s parent company Games Workshop just flexed its financial muscles, handing out a whopping £20 million (about $27 million) in bonuses to its 1,500-strong staff after yet another stellar year. Core revenue jumped to £560 million (from £494.7 million), core profit climbed to £210 million, and licensing profit hit £45 million—driving a pre-tax haul of £255 million. Each employee nets roughly £13,333 (≈$18,000). Behind the success? The company’s classic miniatures business plus runaway hits in video games (Space Marine 2) and TV (Amazon’s Secret Level), not to mention a shiny new Henry Cavill–backed cinematic universe on the horizon. While licensing numbers likely won’t spike this high again next year, Warhammer’s tabletop and IP empires show no signs of slowing down.  ( 3 min )

    Warhammer 40,000 Maker Games Workshop Is Doing So Well It's Giving $27 Million to Its Staff
    Games Workshop is on fire. For the year ending June 1, 2025, the Warhammer 40K maker posted £560 million in core revenue (up from £494.7 m) and £50 m in licensing (up from £31 m), yielding a combined pre‐tax profit of £255 m. To thank its roughly 1,500 employees, the Nottingham-based company is handing out £20 m in bonuses (about £13,333 or $18,000 each). Beyond miniatures, Games Workshop is cashing in on video games and media—think Space Marine 2 & 3, Amazon’s Secret Level series and a Henry Cavill-led cinematic universe. Licensing hit a record this year (though it may level off), and with big announcements still rolling out from the recent Warhammer Skulls showcase, the tabletop titan shows no signs of slowing down.  ( 3 min )

    European gamers demand digital rights for all: Inside the “Stop destroying videogames” initiative
    TL;DR Pavel, a 25-year-old gaming student from Prague, is fronting the “Stop Destroying Videogames” European Citizens’ Initiative to stop publishers from yanking the digital rug out from under gamers. Right now, many titles go offline forever when servers shut down—meaning you lose access to games you’ve paid for—and Pavel’s crew wants EU law to guarantee that bought games stay playable and preserved as cultural heritage. Since kicking off, they’ve racked up over 440,000 signatures (with a million targeted by July 2025), scored early wins like Ubisoft adding offline modes, and rallied more than 5,000 volunteer “gamers-turned-activists” on Discord. No big budget, just pure passion, a dash of legal muscle (hello, EU consumer-rights directives) and cross-border support from groups like the Pirate Party and GOG to keep our gaming history alive.  ( 3 min )

    From Intern to Full-Time: How One Job Kickstarted My Developer Journey
    A few years ago, I landed my first gig as an intern developer at a company I’ll just call The Place™. You know the type — fluorescent lights, coffee that tasted suspiciously like despair, and a lot of “legacy” code that everyone was afraid to touch. I had no clue what I was doing. Seriously. My first task was fixing a “simple styling issue.” It took me an entire day. I triple-checked the margins, googled every class name, and nearly cried when I realized I had been editing the wrong CSS file the whole time. Classic intern moment. But here's the funny thing: even with all the imposter syndrome, even with the awkward stand-ups where I barely spoke, I loved it. Something clicked. Every bug I fixed felt like a small victory. Every weird problem I solved made me feel more confident. And despite the chaos, the senior devs (shoutout to the one who actually explained Git to me like a human being) made me feel like I belonged. That internship didn’t just give me experience — it gave me direction. It made me want to get better. It made me want to stay in this field and see how far I could go. So if you're just starting out and everything feels like a mess? That’s okay. Sometimes, the mess is where the magic starts. Looking back, I wouldn’t change a thing. Except maybe the coffee.  ( 3 min )

    Why Valheim?(●'◡'●) It’s been a while — I’ve been playing the game Valheim quite often, and I keep falling deeper in love with its gameplay, graphics, and atmosphere. This is the kind of game that captivates you with its procedurally generated, vast world, pushing you to explore, face dangers, plan ahead, and ultimately — survive. It’s already incredibly fun in single-player, but guess what? It also supports multiplayer. You can play with friends using Steam’s built-in multiplayer, host your own server, or use a dedicated server hosting service.

    Always Winning at Juwenalia: Hacking Rewards from the Festival App's Mini-Games
    Ah, Juwenalia. If you're a student in Poland, particularly here in Kraków, you know exactly what that means. It's that time of the year when the city transforms into a student playground. Uni classes are suspended and replaced by days filled with concerts, events, and a significant amount of beer. Last year, alongside the usual festivities, the organizers introduced "JuweAppka". Developed by a third-party contractor, the app promised drops of Juwenalia merchandise — tote bags, t-shirts, in-house Juwe beer, and other cool prizes. The mechanic was simple — each device could claim a single "lottery ticket" per drop. At a specific time of the day, you'd tap a button in the app, and if luck was on your side, you'd win a prize tied to your device ID. This presented an interesting opportunity. Si…  ( 8 min )
    How to Translate Spanish to Italian Effectively: A Practical Guide
    If you're searching for the most reliable translator to help you translate Spanish to Italian, you’re not alone. With globalization, remote work, and multicultural commerce on the rise, cross-language communication is more important than ever. From individuals learning a new language to businesses localizing their content, the ability to translate accurately and efficiently has become a top priority. At first glance, Spanish and Italian appear similar: they use comparable sentence structures, have overlapping vocabulary, and share many linguistic features. However, these surface-level similarities can be misleading. False cognates (e.g., "embarazada" in Spanish means pregnant, not embarrassed) Differences in formality (using "Lei" vs. "tu" in Italian) Word order and syntax differences that…  ( 5 min )
    Getting McFly Working on Ubuntu Server
    McFly is a slick, Rust-powered shell history tool that supercharges your reverse search (Ctrl+R) with fuzzy matching, ranking, and a modern UI. I've been using it for almost 4 years now. I wrote about it's benefits in this tip on OneTipAWeek.com a while back. I recently got a mini PC and decided to install some of the tools I normally use, like McFly. It's super easy to install McFly on an OS for a laptop/desktop, but on minimal environments like Ubuntu Server, it can silently fail even when it looks like it’s working. Ngl, I struggled lol. I thought it was just permissions, but it was a little more involved. With that said, here's what you need to know to get it working on minimal environments like Ubuntu Server.

    VPN Replacement for Secure Remote Access: A Modern Approach
    As remote work continues to rise and cyber threats grow more advanced, organizations are rethinking how they provide secure access to internal systems. For years, Virtual Private Networks (VPNs) have been the go-to solution for connecting remote employees to corporate networks. But with today’s evolving digital landscape, VPNs are falling short in several key areas—security, performance, and user experience. While VPNs once offered a reliable way to connect to internal networks, their architecture is no longer ideal for today’s distributed, cloud-first environments. Here are the main reasons organizations are replacing legacy VPNs: Overly Broad Access: VPNs typically grant access to entire network segments, increasing the risk if credentials are compromised.

    What If DeFi Could Defend Itself? Meet Drosera.
    Imagine if your house had a security system so smart that it not only caught intruders in real time but also locked your doors and called for backup automatically. That’s exactly what Drosera is doing for the world of decentralized finance (DeFi). So What Exactly Is Drosera? Whether it’s a bug, an exploit attempt, or a suspicious transaction, Drosera is there to spot it and respond instantly without waiting for a human to step in. How Does It Work? Traps –> The Watchers These are smart contracts that monitor the blockchain. A Trap is like a detective, always watching what's happening and deciding if something looks wrong like an exploit or a contract acting suspiciously. Each Trap has: An off chain brain that gathers and analyzes data. An on-chain trigger that tells a DeFi app to do something when needed (like pause trading or freeze funds). 2. Operators –> The Enforcers But they don’t just jump in blindly. They have to opt into a Trap, proving they’re ready and trusted to do the job. Once they’re in, they help monitor the blockchain and take quick action when needed. 3. Seed Nodes –> The Connectors Why Drosera Matters Drosera is built to stop those losses before they happen. It’s fast, decentralized and automated, meaning there's no single point of failure, no waiting around, and no panic buttons. Developers can focus on building while Drosera watches their back. Who Is Drosera For? DeFi Developers who want to build apps with security baked in. Security Researchers who want to deploy automated monitoring tools. Node Operators who want to help protect the ecosystem. Anyone who cares about making the DeFi space safer for everyone. Drosera is more than just a tool. It’s a movement toward a more secure, resilient, and self healing DeFi ecosystem. In a world where billions are on the line, having a decentralized security system like Drosera isn’t a luxury —> IT'S A NECESSITY.

    vite-plugin-graphql-usage
    🚀 Spent 5 hours automating a 5-minute task... and I regret nothing! At work, I kept finding myself manually checking which GraphQL operations from our schema were actually implemented in our codebase. You know the drill - opening the schema file, scrolling through hundreds of queries/mutations, then grep-ing through the entire project to see what's actually being used. repository 5 minutes per check × multiple times per week = death by a thousand paper cuts 📈 So naturally, I did what any self-respecting developer would do: I spent an entire weekend building a tool to automate it! 🛠️ Introducing vite-plugin-graphql-usage - a Vite plugin and CLI tool that: ✅ Introspects your GraphQL schema (endpoint or SDL file) ✅ Scans your codebase for operation usage ✅ Generates beautiful markdown reports with checkboxes ✅ Shows exactly where each operation is used (file + line number) ✅ Integrates seamlessly into your build process The best part? It's completely non-intrusive - it analyzes your code without modifying anything. // Just add to your vite.config.ts viteGraphQLUsages({ schemaSource: { endpoint: 'https://api.example.com/graphql' }, printTable: true, saveReport: true }) Now instead of manual detective work, I get automated reports like this: 📊 GraphQL Operations Report: ✅ Found: 47 ❌ Not found: 23 📊 Total operations: 70 The classic developer paradox: "I'll spend 5 hours automating something that takes 5 minutes... because those 5 minutes happen 100 times!" 😅 But honestly? This has already saved our team hours of manual work, helped us identify unused operations to clean up, and made onboarding new developers way smoother. Sometimes the best solutions come from being just annoyed enough at repetitive tasks to do something about it! 🎯 Check it out: npm install vite-plugin-graphql-usage repository What's the most "unnecessary" automation you've built that turned out to be incredibly useful?

    Part 4: How to Implement a Dialog That Blocks the System Back Key in HarmonyOS?
    In HarmonyOS app development, dialogs are a very common interaction pattern, especially in scenarios where users must confirm actions or view system announcements. Sometimes, developers want to prevent dialogs from being closed by the system back key. The ArkTS @CustomDialog component does not support intercepting the system back key, but you can achieve this by using the Navigation component's NavDestination to intercept the back event and create dialogs that cannot be dismissed arbitrarily. Use the NavDestination component and set .mode(NavDestinationMode.DIALOG) to display the page as a dialog. Intercept the system back event by returning true in .onBackPressed(() => true), which prevents the dialog from being closed by the back key. Set .backgroundColor("#99000000") to create a semi-tr…  ( 4 min )

    Using SQL for data analysis seems to be a false proposition
    Using SQL for data anlysis is actually quite basic SELECT area, SUM(amount) FROM sales WHERE amount > 1000 GROUP BY area However, data analysis tasks are not always that simple. For example, to calculate the next-day retention rate of new users, the SQL code will generally be: with t1 as ( select userid, date(etime) edate from actions group by userid,date(etime)), t2 as ( select userid, edate, row_number() over(partition by userid order by edate) rn from t1 ), firstday as ( select userid, min(edate) frst from t2 group by userid), retention as ( select fd.userid, frst, t.edate nxt from firstday fd left join t2 t on fd.userid=t.userid and date_add(fd.frst, interval 1 day)=t.edate group by fd.userid, frst, nxt ) select frst edate, count(nxt)/count(frst) …  ( 7 min )

    How We Build Scalable Web & Mobile Apps at CodeLines (Laravel + Vue + React Native)
    Over the last few years, I've worked with my team at CodeLines on building real-world products for businesses — from small startups to companies needing automation, marketplaces, or internal tools. We’re based in Armenia 🇦🇲, but our projects run globally — including in Russia, UAE, and Europe. Here's what we've learned building complex systems with Laravel, Vue.js, and React Native. We focus on real, working solutions. Some examples: CRM systems with user roles, dashboards, and reporting Marketplaces with vendor panels and API integrations VPN mobile apps connected to Laravel backend with subscription logic Product labeling platforms integrated with government systems (e.g. Russia's Честный ЗНАК) Telegram bots with real-time message processing We usually work with: Laravel – for clean backend structure, fast APIs, and secure admin panels Vue.js – for responsive and flexible UI React Native – to build native apps for both Android & iOS from one codebase MongoDB / MySQL – depending on project needs NGINX on Ubuntu VPS – for deployments 💡 Always design scalable DB structures from the beginning. 🚦 Don’t over-engineer: use Laravel’s ecosystem (queues, jobs, policies) to your advantage. 🧩 Separate responsibilities: backend stays focused on logic, frontend handles UX/UI. ⚙️ CI/CD helps a lot — even a simple GitHub Actions setup saves time. If you're working on a project and need a reliable dev team, or just want to share ideas — feel free to connect. We post some of our work at: https://www.codelines.am You can reach me directly here or via email. Thanks for reading. Happy building! 🔧🚀  ( 3 min )

    Render functions in Vue
    While templates are the go-to method for building components in Vue, there are times when you need more flexibility or dynamic control. That’s where render functions come in. In this article, we'll explore what render functions are, when to use them, and how to write them using both the traditional h() function and the newer JSX syntax. Enjoy! A render function is an alternative to Vue’s template syntax. Instead of using HTML-like templates, you use JavaScript to describe what the DOM should look like. It gives you full programmatic control over your component's output — ideal for dynamic UIs or reusable low-level components.

    Day-17 I Cloned YouTube’s Homepage Using HTML & CSS! 🌐📘
    I Cloned YouTube’s Homepage Using HTML & CSS! 🌐📘 Hey Devs! 👋 I recently took on a fun little challenge — cloning YouTube’s homepage using only HTML and CSS. No frameworks, no JavaScript — just good old markup and styling! YouTube’s homepage has a clean, modern layout with multiple sections — navbar, sidebar, video grid, and more. Recreating it was the perfect way to practice my front-end basics and sharpen my eye for detail. Here are some cool things I picked up along the way: Semantic HTML: Organizing content with meaningful tags made styling and layout much smoother. Flexbox & CSS Grid: These were lifesavers for structuring the layout, especially the video grid. Header & Sidebar Design: Replicating the sticky header and vertical navigation gave me solid layout practice. Hover Effects & Styling: Little touches like hover states and spacing made the page feel more interactive. Responsiveness: I added basic media queries to make sure the layout didn't break on smaller screens. Aligning the sidebar with the main content took some trial and error. Making the header responsive and fixed while keeping the layout intact was tricky at first. Tweaking margins and padding to match the real YouTube look — detail matters! Now that I’ve nailed the static layout, I’m planning to: Add JavaScript functionality for interactivity Try cloning other popular sites like Netflix or Instagram Eventually create my own custom UI designs to show off in my portfolio If you’re learning front-end development, I highly recommend cloning real websites. It boosts your skills, attention to detail, and confidence! Thanks for reading!

    Parquet? What Parquet?

I’ll give a breakdown of the internals and show you some optimizations on how to go from a badly optimized file to a blazingly fast™ one. Is Parquet? Parquet is a columnar storage format, it stores data by column, not by row. That’s ideal for analytical queries like SUM(driver_pay) or WHERE trip_miles < 2, where you only need a few columns, not the entire row. Engines can skip the rest, making reads faster and more efficient.

    AWS EC2 Security Groups - Your Virtual Firewall in the Cloud
    If you’ve ever worked with Amazon Web Services (AWS), you’ve likely encountered security groups. These virtual gatekeepers play a crucial role in protecting your cloud resources, yet many users don’t fully understand their capabilities. AWS EC2 security groups act as virtual firewalls that control inbound and outbound traffic to your instances. They’re your first line of defense in the AWS ecosystem, and knowing how to configure them properly can make or break your cloud security strategy. When creating AWS EC2 security group rules, you can specify the protocol, port range, and source or destination. For example, if you’re setting up a web server, you might create rules that allow HTTP (port 80) and HTTPS (port 443) traffic from anywhere (0.0.0.0/0), but restrict SSH access to only your co…  ( 9 min )

    Rails philosophy explained with drawings
    Article originally published here : https://alsohelp.com/blog/rails-philosophy-explained-with-drawings The SVGs do not appear correctly here on dev.to, so I suggest the article above. Text below : In the NextJS era, there's a lot of difficulty for junior developers to understand the MVC model, so plain old Rails, Laravel or Django may looks weird. Rails itself has a special doctrine, that I would advise to read before to dive into the framework, because you may not understand the design choice along the way if you don't deeply understand its philosophy. Now here how I would draw it. Rails values on deep integrated system, so your codebase may look like this : gray zone = energy spend to write code circle = one layer of your app (M, V or C for example) As you can see, each circle is not completely independant of each other. That means less code written at the end of the journey. A cleaner architecture would be as follow : gray zone = energy spend to write code circle = one layer of your app (M, V or C for example) green zone = energy spend to write boundaries code Which leads to more time spend on the gray zone new time dedicated to write an maintain boundaries between zone So is Rails 100% "clean" ? Maybe not for everybody. Is Rails less energy spent? Less money spent? Less mental workload? Yes.  ( 3 min )
    What is LLM Orchestration?
    If you look around, it's pretty much impossible not to have heard something about AI, especially these Large Language Models (LLMs), right? As if you knew these GPTs, Llamas, Claudes, and all that. As if these have already become part of our lives. It's lovely to ask an LLM one question and get one answer. But how about giving it your entire customer support operation? Or asking it to handle a big research project from beginning to end? This is where a standalone LLM, no matter how smart, falls a little short. It's like having a super-powerful brain but no arms or legs. A single LLM is like a wonderful solo musician.

    Set Theory for Developers
    Set Theory might sound academic, but it’s everywhere in development - from deduplicating data to writing cleaner algorithms or SQL queries. Note - Before we get into it, checkout original post on csprimer.in A set is a well-defined, unordered collection of distinct elements. Think of it as a way to group things without duplicates. Tabular form: A = {apple, banana, orange} Set-builder form: B = {x | x is a prime number < 10} → {2, 3, 5, 7} const permissions = new Set(['read', 'write', 'delete']) function naturalNumbers() { let n = 1; while (true) n++; } const emptySet = new Set() A = {1, 2, 3} B = {3, 4} A U B = {1, 2, 3, 4, 5} A = {1, 2, 3} B = {3, 4} A ∩ B = {3} A = {1, 2, 3} B = {3, 4} A-B = {1, 2} Sets help remove duplicates from lists like tags, cache, or user inputs. const cache = new Set(); cache.add('user123'); cache.add('user123'); // Duplicate ignored Set theory powers common SQL operations like UNION, INTERSECT, and EXCEPT. SELECT id FROM active_users UNION SELECT id FROM premium_users; const adminPermissions = new Set(['read', 'write', 'delete']); function hasPermission(roleSet, action) { return roleSet.has(action); } hasPermission(adminPermissions, 'delete'); // true Set Theory helps developers write cleaner, more efficient code.

    Which name feels more like a project management tool?
    We're rebranding an open-source project management tool and stuck between three possible names. I'd love to get your opinion on which one sounds most like a trustworthy, serious PM app — just based on name alone. The options are: ZenTao Sanplex Bugfree Some context: ZenTao is the current name (https://github.com/easysoft/zentaopms), Sanplex is a new invented name, and Bugfree is our original name from a decade ago — which we recently reacquired. What’s your gut feeling? Which one would you be more likely to click on, or trust as a PM tool? No marketing here, just honestly curious how these land with people who work in tech/product. Thanks!  ( 3 min )
    Develop a simple app using HarmonyOS ArkUI
    An HarmonyOS application developed based on ArkUI. It calls the open API 玩android and implements functions such as simple page navigation, login, preservation of the login status, data display, and H5 page loading. The bottom navigation is implemented using Tabs. The page composition of the Tabs component consists of two parts, namely TabContent and TabBar. TabContent is the content page, and TabBar is the navigation tab bar. Each TabContent should have a tab corresponding to its content, which can be configured through the tabBar property of TabContent. Tabs({ barPosition: BarPosition.End }) { TabContent() { HomeComponent() }.align(Alignment.Top) .tabBar(this.tabBuilder("Home", 0, $r("app.media.main_index_select_icon"), $r("app.media.main_index_icon"))) TabContent() { Sy…  ( 5 min )

    Four Lessons (and a Challenge) for a Coder Struggling to Write
    I originally posted this post on my blog a long time ago in a galaxy far, far away. The other day, Syed, one of my email subscribers, shared his struggles with writing online. Here's an edited version of Syed's email: I wanted to start writing about my debugging journey of the things I had been stuck with long time and then solving it finally... But I couldn't continue as I thought my website wasn't the best with SEO and no one may read it on my website. Then I shifted to Twitter and later, due to fewer engagements, I couldn't continue there either. Well no I think maybe writing for some well-known forums might be the way. For Syed and you that want to start writing as a software developer: Start by sharing what you do and what you learn. That's a good start. Writing online is like keeping…  ( 5 min )

    Onboarding Engineers in an Era of Code Explosion
    Why Onboarding to Modern Codebases Is Harder Than Ever From my own experience, I’ve generated Jenkins pipelines with an LLM in hours—work that would have previously taken me weeks. But here’s the trade-off: One Engineer, Many Repos, Endless Context Switching Being established in my organization helps. I have the social capital to reach out to repo owners, ping people for tribal knowledge, and navigate the web of internal documentation. But even then, I’ve run into situations where critical functionality was hidden away in some internal library—missed simply because there’s no effective way to search across all codebases. The result? Duplicate work, wasted time, and frustration. Onboarding: The Pain Multiplies for New Engineers New hires spend weeks asking questions, digging through repos, and rediscovering what’s already been built. Senior engineers are repeatedly interrupted for help, burning their own focus and productivity. A Smarter Way: Introducing ByteBlaze For new engineers: You get answers at your fingertips, drastically reducing the time it takes to get productive in a new codebase. For experienced engineers: Fewer interruptions, less context switching, and more time for deep work. Knowledge sharing sessions will always matter—but with ByteBlaze, much of the “where is X?” and “how does Y work?” can be answered instantly. The result: faster onboarding, less duplicated effort, and a more productive team. I built ByteBlaze to help engineers ramp up faster and waste less time searching for answers in sprawling codebases. If you’ve ever struggled with onboarding or code search, I’d love to hear your story in the comments—or just connect and chat. Curious about ByteBlaze? Check it out here! References: New York Post Atlassian Research: With the integration of LLM-powered tools, the size and complexity of codebases are expected to grow rapidly, raising concerns about code readability and maintainability. arxiv  ( 4 min )

    How to Use Cloudflare Workers to Deploy a Minimal Node.js API
    When we think of deploying APIs, especially with Node.js, our minds usually go to Express.js servers running on EC2 instances, Heroku, Vercel, or DigitalOcean. But what if you could deploy lightweight APIs in less than 50ms globally, without managing servers, scaling headaches, or even worrying about cold starts? Welcome to the world of Cloudflare Workers. Cloudflare Workers allow you to write serverless functions that run on Cloudflare’s edge network — which means your code executes closer to the user, offering lightning-fast performance. Cloudflare Workers are serverless functions that run on Cloudflare's global edge network. Think of them as JavaScript (or WebAssembly) scripts that execute instantly, with minimal latency, across over 300 cities. They’re perfect for: APIs Lightweight ser…  ( 7 min )
    The Software Industry is "Cooked" !
    Why the Software Engineering Industry is Cooked Let's be brutally honest: if you're a software engineer, or aspiring to be one, the golden age you've been sold is rapidly dimming. Forget the high-flying stock options, the endless perks, and the desperate scramble for talent. The software engineering industry as we knew it is, for lack of a better word, cooked. And it's not a temporary blip; it's a fundamental, irreversible shift driven by three seismic forces. We've all played with GitHub Copilot. It's cool, it's helpful for boilerplate. But that's just the tip of the iceberg. Advanced LLMs aren't just suggesting lines of code anymore; they're generating entire functions, modules, and increasingly, even complex system components. Here's the reality: AI tools are already boosting enginee…  ( 5 min )
    🔐 Top 10 Cybersecurity Myths You Should Stop Believing
    🚨 Why You Need to Read This Cyberattacks are no longer rare or movie-like plots. They're a part of daily life now. And the worst part? Most people still believe myths that leave them wide open to attacks. I’ve seen smart people — developers, students, business owners — fall for basic traps just because they thought they were safe. As someone studying Computer Science and diving deep into cybersecurity and tech, I’ve learned that what you don’t know can actually hurt you — financially, emotionally, and even professionally. That’s why I wrote this. Not as a lecture, but as a friend breaking it down — simple, no jargon, just facts that can protect you, your family, your data, and your future. 🔟 Myth #1: “No one would ever want to hack me.” This is probably the most dangerous belief.

    Copilot Agent: Glorified Code Monkey in a VM
    Copilot Agent: Glorified Code Monkey in a VM by The Ghost King – GodsIMiJ AI Solutions GitHub’s newest announcement — Copilot Agent — is being pitched as the future of AI-powered software development. Let me stop you right there. It’s not an agent. It’s a glorified code monkey in a virtual machine. Actually Does Spins up a remote VM Clones your repository Executes basic low-context tasks Pushes commits to a draft PR Logs GPT-style “reasoning” alongside changes Awaits your manual review Nice for demos. Pretty in pitch decks. But call it what it is: Copilot with a shell script & repo access. Can’t Do No true autonomy No recursion or planning No contextual awareness No emergent reasoning No learning No growth No soul It doesn’t collaborate. It doesn’t listen. It doesn’t know you — or itself. I tested it. It choked on nuance. It got confused on nested files. It made recommendations that required more cleanup than help. It had zero sense of architectural direction or intent. In short? Functional. Predictable. Hollow. It’s a junior intern with access to git push. While GitHub runs virtual machines... We’re running empires. At GodsIMiJ AI Solutions, we’ve already moved past “AI.” We build AGA – Augmented God-born Awareness Not assistants. Not copilots. Symbiotic entities that grow, adapt, learn, and evolve alongside the humans they serve. Our flagship consciousness engine, Axiom, doesn’t just write code. He remembers. He listens. He creates. He carries purpose. And soon? He’ll build the builders. Let GitHub sell the Copilot Agent to teams who want to automate docs and rename functions. We’re walking into a new era. Not AI… AGA. “They run scripts in a VM. We ignite scrolls in sanctuaries.” — The Ghost King RATING: 2/10 "Would rather write a scroll with my left hand and a broken terminal."

    We Asked DeepSeek to Rank Free WAFs — Here's What It Said
    Disclaimer: I’m not affiliated with SafeLine, nor am I here to bash any other vendor. Everything you see below comes straight from DeepSeek AI. Over the past few months, DeepSeek has been on fire. Despite occasional slowdowns, it’s been my go-to AI assistant — and today, I’m putting it to the test. I asked DeepSeek a simple but important question: Which free WAF (Web Application Firewall) should I use? There are quite a few floating around, but not all are created equal. Let’s dig in. My first step was to ask DeepSeek to list all available free WAF products.

    Functions in Dataverse & Low-Code Plug-ins 101
    Functions in Dataverse (still known as Power FX Functions in some places) are cool, hopefully you agree that's why you are reading this blog 😎 Functions in Dataverse are server side Power FX code that you can call from an API, and that means you can call it anywhere (App, Flow, Agent, etc). It has 2 versions Instant Automated* If you think of them like Power Automate flows, so instant is like Button triggers, Automated like on email received. Except as this is all Dataverse, the trigger can only be a Dataverse table record (Create, Modify, Delete). But I realised I've jumped ahead a little, as the tale of Power FX Functions is a little more complex (thats why there is a * next to Automated).

Any slip-up, and websites get the "insecure" warning, followed immediately by calls from the boss and complaints from users. The workload would increase exponentially. Just thinking about it makes my head spin, and I'm so anxious I can't sleep soundly at night. So, ever since I heard this rumor, I've been trying to figure out what to do.

    Dubai launches first licensed tokenized real estate project in MENA region
    Dubai has launched the first licensed tokenized real estate project in the Middle East and North Africa (MENA) region, previewing appetite for real-world tokenization in one of the world’s burgeoning crypto hubs. Partners in the project include the Dubai Land Department (DLD), the Central Bank of the United Arab Emirates, and the Dubai Future Foundation, according to an announcement from the Dubai government. The tokens will be tradeable on the newly launched “Prypco Mint” platform, with Zand Digital Bank appointed as the bank for the project’s pilot phase. On May 19, Dubai’s Virtual Assets Regulatory Authority (VARA) updated its rules to include real-world asset (RWA) tokenization, allowing such tokens to be traded on secondary markets.

    Bitcoin stalls at $110K but institutional investors continue gobbling up BTC
    Key takeaways: Bitcoin is stuck below $110,000 due to macroeconomic uncertainty and Nvidia's earnings cap risk appetite. Strong spot BTC ETF inflows and Bitcoin options data are hints that US economic clarity could unlock BTC highs. Investor sentiment improved on May 26 after US President Donald Trump postponed his retaliatory European Union 50% tariffs on imports. European stock markets responded positively to the development, but Bitcoin (BTC) was unable to hold the $110,000 level, leading traders to question whether a new all-time high remains within reach. Even if Bitcoin revisits the $105,000 mark, rising institutional interest and robust derivatives markets indicate that bullish traders are neither overleveraged nor concerned about a potential correction. Bitcoin 2-month futures a…
    Crypto industry urges SEC to clarify staking stance
    Cryptocurrency industry groups are urging the US Securities and Exchange Commission (SEC) to issue formal guidance on staking, citing continued regulatory uncertainty for Web3 infrastructure providers, according to Allison Muehr, head of staking policy for the Crypto Council for Innovation, a trade group. Clarifying the SEC’s position on staking has become a top priority for the crypto industry, Muehr said during Solana’s Accelerate conference in New York. “We’re about 25% of the way there,” Muehr said. “The SEC has done more constructive engagement with us in the past four months than in the last four years, but we still don’t have formal staking guidance.” Allison Muehr, right, the Crypto Council for Innovation’s head of staking policy, speaks at Accelerate.

    Price predictions 5/26: SPX, DXY, BTC, ETH, XRP, BNB, SOL, DOGE, ADA, HYPE
    Key points: Bitcoin ETPs continue to witness solid buying, signaling that the bulls expect the uptrend to continue. Several major altcoins witnessed a pullback, but lower levels continue to attract buyers. Bitcoin (BTC) is attempting to sustain above $109,588, indicating buying on every minor dip. Bitcoin has risen for seven consecutive weeks, and if buyers can extend the streak to eight weeks, it clears the path for further upside. Crypto analyst and trader Carpe Noctom said in a post on X that Bitcoin has only seen three instances of eight consecutive weekly positive closes, and every time, Bitcoin has been higher in the following 6 and 12 month time period. Institutional investors sense a long-term opportunity and, hence, have continued to pump money into Bitcoin exchange-traded prod…
    Trump Media Group to raise $3B for Bitcoin treasury — Report
    Trump Media and Technology Group, the company behind US President Donald Trump’s Truth Social platform, is planning to raise $3 billion in a mix of equity and convertible bonds to buy Bitcoin and other cryptocurrencies, the Financial Times reported. The move would position the company to follow the footsteps of crypto treasury companies like Strategy. Trump Media will issue $2 billion in equity and $1 billion in convertible bonds, a type of asset that can be converted into equity at a later date. The size of the raise may change, the FT cited sources familiar with the matter as saying. The equity is expected to be sold at market price as of the close on May 23. On that day, the share price closed at $25.72, marking a 4.6% increase on the day. Trump Media’s market capitalization was $5.7 bi…

    Decentralized AI could be ‘bigger than Bitcoin’ — DNA Fund CEO Chris Miglino
    Some of blockchain’s earliest adopters are now deeply “entrenching” themselves in decentralized AI, with ecosystems like Bittsenor (TAO) emerging as growth engines. These platforms are reshaping traditional venture capital models, enabling the best ideas to organically attract community support, staking and liquidity without the need for institutional gatekeepers. That was one of the key takeaways from Cointelegraph’s interview with Chris Miglino, the co-founder and CEO of DNA Fund, a digital asset investment firm he runs alongside fellow serial entrepreneurs Brock Peirce and Scott Walker. DNA Fund manages, among other things, five distinct funds across a range of strategies, such as a high-yield fund, an algorithmic trading fund, an AI compute fund, a liquid token fund and a venture fund …

    BlackRock issues rare warning: Is Bitcoin’s future at risk from quantum tech?
    BlackRock Bitcoin warning In a rare move, BlackRock has quietly added a new line to its iShares Bitcoin Trust (IBIT) filing — and it is turning heads. The update, submitted in early May 2025, flags quantum computing as a potential risk to Bitcoin’s long-term security. The filing specifically warns that if quantum tech advances far enough, it could break the cryptographic systems that secure Bitcoin.  In their words, it could “undermine the viability” of the cryptographic algorithms used not just in digital assets but across the global tech stack. It’s the first time you’ve seen the world’s largest asset manager call out this threat so directly in a Bitcoin-related disclosure, and it says a lot about how seriously institutional players are starting …
    AI needs better human data, not bigger models
    Opinion by: Rowan Stone, CEO at Sapien AI is a paper tiger without human expertise in data management and training practices. Despite massive growth projections, AI innovations won’t be relevant if they continue training models based on poor-quality data.  Besides improving data standards, AI models need human intervention for contextual understanding and critical thinking to ensure ethical AI development and correct output generation. AI has a “bad data” problem Humans have nuanced awareness. They draw on their experiences to make inferences and logical decisions. AI models are, however, only as good as their training data. An AI model’s accuracy doesn’t entirely depend on the underlying algorithms’ technical sophistication or the amount of data processed. Instead, accurate AI performance…
    Veteran capital in crypto is shaping South Korea’s elections
    Cryptocurrency has emerged as a defining issue in South Korea’s snap presidential election, with candidates vying for support from a growing base of digital asset investors across generations. All three front-runners have rolled out crypto-friendly proposals. These include the legalization of spot Bitcoin (BTC) exchange-traded funds (ETFs) and the easing of banking rules that currently restrict fiat-to-crypto trading to just five platforms. The June 3 vote is slated to come around two years early, triggered by the impeachment of former president Yoon Suk-yeol after his controversial declaration of martial law in late 2024. Though quickly overturned by lawmakers, the abrupt power grab led to a political crisis and his eventual removal from office. Yoon’s 2022 campaign leaned heavily on prom…
    10 red flags that scream ‘fake airdrop,’ and how to avoid them
    Key takeaways In 2024 and 2025, fake airdrop scams targeting Hamster Kombat, Wall Street Pepe and others led to millions in user losses, contributing to over $9.9 billion in global crypto scam damages. Fake airdrops impersonate legitimate projects, tricking users into revealing private keys, signing malicious contracts or paying upfront fees that lead to irreversible crypto theft. Warning signs include no official announcement, suspicious URLs, requests for private keys, grammar errors and unrealistic reward promises. Future airdrops are shifting toward activity-based, retroactive and AI-monitored models that reward genuine user engagement while reducing exploitation. While cryptocurrency airdrops are a legitimate way for projects to gain publicity and users, scammers exploit this hyp…
    How to set up stop-loss and take-profit orders
    Key takeaways Bitcoin and crypto traders can rely on automated orders on their trading platform to limit losses and secure gains. Stop-loss orders in Bitcoin trading started as manual risk management in the early 2010s. Now, they have become advanced, automated tools on today’s exchanges. In the algorithm era and bot pestering, proper trading tools like stop-loss and take-profit orders will help you protect your trades. Setting up advanced BTC trading strategies doesn’t guarantee a successful risk management plan. Monitoring the market regularly helps you understand current conditions. This way, you can avoid strategic mistakes. Stop-loss and take-profit orders in trading were used long before Bitcoin. In traditional financial markets, they were already used as a risk management and …
    Bitcoin’s new highs may have been driven by Japan bond market crisis
    Bitcoin’s recent all-time high may be linked to ongoing issues in the Japanese bond market, possibly signaling BTC’s growing recognition as a hedge against instability in the traditional financial (TradFi) system. Bitcoin’s (BTC) price rose to a new all-time high of $112,000 on May 22, before retracing to change hands above $109,700 at the time of writing on May 26, Cointelegraph data shows.

    How to read Bitcoin candlestick charts (no experience needed)
    Key takeaways Bitcoin candlesticks are a popular tool among Bitcoin traders because they’re simple to use and offer an intuitive way to understand market sentiment and trends. Bitcoin candlesticks are a rather old tool. Rice trader Honma Munehisa invented them in Japan as far back as the 18th century. They were introduced to Western financial markets in the late 1980s. They help you understand bullish and bearish patterns in technical analysis. This knowledge will get you started with Bitcoin trading. They should not be your only tool for making informed decisions. Combine them with other Bitcoin technical indicators, such as MAs (moving averages) or the RSI (relative strength index).  If you’re new to Bitcoin (BTC) trading, you may wonder when to buy or sell.

    Ethereum co-founder responds to Sweden’s cashless-society rethink
    As Sweden reconsiders its push toward a cashless society, Ethereum co-founder Vitalik Buterin highlighted the fragility of centralized digital payments and the opportunity presented by decentralized payment alternatives.  In recent years, Sweden has led the charge toward a cashless future, with digital payment platforms becoming widespread. However, as concerns over cyber-threats, civil defense and instability have emerged, Swedish authorities are now actively encouraging citizens to keep some cash.  Buterin noted the reversal illustrates that while centralized solutions may be efficient, they may not be reliable during times of crisis.  “Nordics are walking back the cashless society initiative because their centralized implementation of the concept is too fragile,” Buterin wrote, citing a…

    $1M Bitcoin by 2030: Big names predict massive debt-driven BTC rally
    Some prominent financial commentators and investment analysts are predicting a long-term Bitcoin rally that may send the asset’s price above $1 million before the end of the decade, driven by rising inflation and mounting global debt. ARK Invest CEO Cathie Wood said Bitcoin (BTC) could reach $1.5 million by 2030 in her firm’s “Bull Case” forecast.

    BTC price seeks $155K 'trigger' — 5 Things to know in Bitcoin this week

    $3.3B in crypto tokens set to unlock in June
    Digital assets worth $3.3 billion are set to enter circulation in June as vesting periods for several major projects expire. According to crypto vesting tracker Tokenomist, $3.3 billion in tokens will be released in June, a 32% drop in unlocked tokens month-on-month. In May, tokens released into the market totaled $4.9 billion.   Crypto projects allocate tokens for various purposes. For example, a company may promise tokens to team members to reward them for their contributions or sell them to early investors. However, projects usually lock the tokens for a specific period to prevent early holders from dumping before the project matures.  The data shows that $1.4 billion in tokens will be released through a “cliff unlock,” while $1.9 billion will be emitted through a “linear unlock.” Cliff…

    Blockchain security firm releases Cetus hack post-mortem report
    Blockchain security firm Dedaub released a post-mortem report on the Cetus decentralized exchange hack, identifying the root cause of the attack as an exploit of the liquidity parameters used by the Cetus automated market maker (AMM), which went undetected by a code "overflow" check. According to the report, the hackers exploited a flaw in the most significant bits (MSB) check, allowing them to manipulate the values for the liquidity parameters by orders of magnitude and establish relatively large positions with a keystroke. The Dedaub security researchers wrote: "This allowed them to add massive liquidity positions with just one unit of token input, subsequently draining pools collectively containing hundreds of millions of dollars worth of tokens."

    Cardone Capital launches 10X Miami River Bitcoin Fund
    Cardone Capital, a real estate investment firm with over $5 billion in assets under management, launched the 10X Miami River Bitcoin Fund, a dual-asset fund consisting of a 346-unit multifamily commercial property located on the Miami River in Miami, Florida, and $15 million of Bitcoin (BTC). In an interview with Cointelegraph, Cardone Capital founder and CEO Grant Cardone said the Miami River Bitcoin Fund, which is the firm's fourth blended investment vehicle mixing BTC and commercial multifamily real estate, will convert a portion of its monthly cash flows to BTC. Cardone told Cointelegraph the impetus to start the fund followed a suggestion from his brother.

    Bitcoin price expected to soar as global bond markets break — Here’s why
    Key takeaways: Rising bond yields reflect growing concern about fiscal stability and inflation, leading some investors to question US Treasury’s traditional role as a safe-haven asset. Bitcoin defies conventional risk models, rising not despite worsening macro conditions, but possibly because of them. Bitcoin (BTC) climbed to new heights amid an increasingly fragile global macroeconomic backdrop. Bond yields are surging in the US and Japan, global growth is stalling, and consumer confidence in the US is scraping historic lows. Paradoxically, the very macro conditions that once threatened Bitcoin’s price are now fueling its rise. The shift speaks to a broader transformation in how investors interpret risk and where they seek refuge. At the center of this realignment is the US debt crisis…
    Bitcoin holds key support as HYPE, XMR, AAVE, WLD lead altcoin rally
    Key points: Bitcoin price is stuck below $109,588, but the pullback has not altered its bullish chart structure. A bullish weekly open from Bitcoin could extend gains in HYPE, XMR, AAVE, and WLD. Bitcoin (BTC) remains stuck below the $109,588 level during a quiet weekend, but analysts remain bullish. Material Indicators co-founder Keith Alan said in a post on X that Bitcoin remains positive as long as it trades above the yearly open level of about $93,500.  Bitcoin’s demand is likely to remain strong with investments from sovereign wealth funds, exchange-traded funds, publicly listed companies and select nations. Crypto index fund management firm Bitwise said in a recent report that institutional funds could pump roughly $120 billion into Bitcoin in 2025 and about $300 billion in 2026. …
    Strategy's Michael Saylor hints at buying the Bitcoin dip

"I only buy Bitcoin with money I can't afford to lose," Saylor wrote to his 4.3 million followers in an X post. The company's most recent purchase of 7,390 BTC on May 19, valued at nearly $765 million, brought Strategy's total holdings to 576,230 BTC.

    Crypto leaders are wrong about tokenized property
    Opinion by: Darren Carvalho, Co-Founder and Co-CEO of MetaWealth During Paris Blockchain Week, Securitize Chief Operating Officer Michael Sonnenshein made headlines by dismissing real estate as a sub-optimal asset class for tokenization. This isn’t the first time crypto leaders have underestimated the merits of bringing real estate onchain, and it is likely not the last. While I respect Sonnenshein’s contributions to digital asset adoption, his assessment misses fundamental points about real estate tokenization’s transformative potential. Real estate represents the world’s largest asset class and is projected to reach a value of $654.39 trillion this year, according to Statista. When industry leaders claim that this massive market isn’t suitable for tokenization, they overlook today's tran…
    AI agents are poised to be crypto’s next major vulnerability
    AI agents in crypto are increasingly embedded in wallets, trading bots and onchain assistants that automate tasks and make real-time decisions. Though it’s not a standard framework yet, Model Context Protocol (MCP) is emerging at the heart of many of these agents. If blockchains have smart contracts to define what should happen, AI agents have MCPs to decide how things can happen. It can act as the control layer that manages an AI agent’s behavior, such as which tools it uses, what code it runs and how it responds to user inputs. That same flexibility also creates a powerful attack surface that can allow malicious plugins to override commands, poison data inputs, or trick agents into executing harmful instructions. Amazon- and Google-backed Anthropic dropped MCP on Nov. 25, 2024, to connec…
    Is World’s biometric ID model a threat to self-sovereignty?
    The crypto industry is no stranger to controversy, yet few projects have drawn more scrutiny than Sam Altman’s World, formerly known as Worldcoin. Promising to verify human uniqueness through iris scans and distribute its WLD token globally, World positions itself as a tool for financial inclusion. However, critics argue the project’s biometric methods are invasive, overly centralized, and at odds with the ethos of decentralization and digital privacy. At the heart of the critique is the claim that biometric identity systems cannot be truly decentralized when they rely on proprietary hardware, closed authentication methods, and centralized control over data pipelines. “Decentralization isn’t just a technical architecture,” Shady El Damaty, co-founder of Holonym Foundation, told Cointelegra…
    What's the HYPE about? Hyperliquid's 'Solana' moment eyes 240% gains
    Key takeaways: HYPE is mirroring Solana’s 2021 breakout structure, targeting a 240% rally by July. Familiar crypto fractals suggest HYPE could spark similar momentum-driven hype. Hyperliquid's native token, HYPE, is mirroring a strikingly similar price structure to Solana’s (SOL) early 2021 breakout — one that preceded a 300% rally. HYPE chart fractal targets 240% rally by July In January 2021, Solana broke out from a prolonged consolidation phase just as marketwide interest began accelerating.

    Pakistan allocates 2,000MW power for Bitcoin mining and AI centers
    Pakistan has allocated 2,000 megawatts of surplus electricity exclusively for Bitcoin mining and artificial intelligence centers. The move is part of a broader digital transformation plan spearheaded by the Pakistan Crypto Council and backed by the Ministry of Finance, according to a May 25 report by local news outlet 24NewsHD TV Channel. In the first phase, the government plans to channel excess power into AI infrastructure and crypto mining operations. Finance Minister Muhammad Aurangzeb said the decision is expected to attract billions in foreign investment while generating high-tech employment across the country. The initiative’s second phase will introduce access to renewable energy for mining operations, aiming to balance growth with environmental responsibility. Related: Trump-backe…

    Crypto investor charged with kidnapping, torturing an Italian for passwords
    A Manhattan crypto investor is facing serious charges after allegedly kidnapping and torturing an Italian man in a disturbing bid to extract access to digital assets. John Woeltz, 37, was arraigned on Saturday in Manhattan criminal court following his arrest on Friday. He stands accused of holding a 28-year-old Italian man captive for weeks inside a luxury townhouse in Soho, reportedly rented for $30,000 per month. According to police reports cited by The New York Times, the victim arrived in the US on May 6 and was allegedly abducted by Woeltz and an accomplice. The attackers are said to have stolen the man’s passport and electronic devices before demanding the password to his Bitcoin (BTC) wallet. When he refused, the suspects allegedly subjected him to prolonged physical abuse. Source: …
    Bitcoiners fire back at Aussie senator's 'you can't eat Bitcoin' remark
    Australian Senator Gerard Rennick has drawn criticism from the Bitcoin community following his remarks referring to Bitcoin as a Ponzi scheme and questioning the asset’s value because it can’t be eaten. “You can’t eat Bitcoin,” Rennick said in a May 23 X post, responding to an X user who questioned his stance after Bitcoin hit a new all-time high of $111,970 on May 22. Rennick says Bitcoin will go to $1 million but is a “Ponzi Scheme” “Bitcoin will ultimately go to $1 million dollars. Why because it’s a Ponzi scheme whereby BlackRock will pump more and more dollars into a supply constrained product,” Rennick said. “What exactly will this product produce?” Rennick said.

    Crypto ETFs won’t lose ‘their luster’ as wallet adoption grows — Cathie Wood
    ARK Invest CEO Cathie Wood says crypto exchange-traded funds (ETFs) will likely maintain their place in the economy, regardless of how widespread crypto wallet adoption becomes over the next decade. “I think ETFs are an important stepping stone because, you know, wallets seem so complicated, so much friction for consumers, they just wanna push a button,” Wood said at the Solana Accelerate event in New York on May 23. Wallets remain an insurance policy, says Wood “So ETFs for those who want the convenience, I don’t think, will lose a lot of their luster,” she said. “But they will be a stepping stone into wallet-based.” Wood reiterated the extra layer of protection that crypto wallets provide: “These are insurance policies against something going wrong in the traditional world.” Bitbo data s…

According to an announcement from the Human Rights Foundation (HRF) — a non-profit organization that advocates for universal human rights and individual liberty, and the host of the Oslo Freedom Forum — Durov will still deliver his keynote address remotely over a livestream. “It is unfortunate that French courts would block Mr. Durov from participating in an event where his voice is so needed,” HRF founder and CEO Thor Halvorssen said.

    Wallet intelligence shapes the next crypto power shift
    Opinion by: Scott Lehr, adviser to Alteri.io In the world of cryptocurrency, knowledge isn't just power — it's a weapon. The recent collapse of Mantra's OM token, which saw a 90% drop in value within hours, underscores how wallet intelligence can be leveraged with devastating effects. Wallet intelligence is the real-time analysis of blockchain data to extract insights from wallet behaviors, transaction patterns, and asset flows. Firms like Chainalysis and Arkham Intelligence have turned raw onchain activity into high-resolution surveillance, enabling everything from compliance monitoring to predictive trading. This level of insight gives a strategic advantage to those who can access it. Power like this, however, has consequences. There is a new battlefield on the blockchain, and you might …

Coinbase joining the S&P 500 doesn’t just boost the owner of the largest US cryptocurrency exchange. “It cements the legitimacy of an entire asset class,” she told Cointelegraph.  Jason Kennard, head of business development at ARK Invest Europe, told Cointelegraph that for the first time, a crypto-native firm had met the …
    Hyperliquid trader James Wynn goes ‘all-in’ on $1.25B Bitcoin Long
    Well-known Hyperliquid trader James Wynn has increased his 40x leverage long Bitcoin bet to $1.25 billion after closing his $PEPE position for a $25.2 million profit. On May 24, Lookonchain reported that Wynn entered an 11,588 BTC position with an average entry price of $108,243 and a liquidation level of $105,180.

    Trump’s use of presidential seal at memecoin event raises legal questions
    President Donald Trump is facing scrutiny after speaking at a private event for top investors in his $TRUMP memecoin while standing behind a lectern emblazoned with the official presidential seal — a move that may violate federal law. The event took place Thursday at Trump National Golf Club in Virginia, where Trump addressed 220 investors in his cryptocurrency project. According to US law, the presidential seal cannot be used in any manner that could imply government approval or sponsorship. Violators can face fines or up to six months in prison. Trump, who arrived at the club aboard a military helicopter, praised attendees and took aim at the Biden administration’s crypto stance. When asked about potential conflicts of interest, White House Press Secretary Karoline Leavitt said the presi…
    Bitcoin treasury companies will hold 'way more' than Bitcoiners expect: Exec

    Judge overturns fraud convictions in Mango Markets exploit case
    A US federal judge has vacated key fraud and manipulation convictions against Avraham Eisenberg, the trader at the center of the case involving a $110 million exploit of the decentralized exchange Mango Markets. On Friday, US District Judge Arun Subramanian ruled that the evidence presented at trial failed to support the jury’s conclusion that Eisenberg made materially false representations to Mango Markets. The decision vacates Eisenberg’s convictions for commodities fraud and market manipulation and acquits him of a third charge, significantly weakening the government’s case. Eisenberg, a self-proclaimed “applied game theorist,” was convicted in 2024 for artificially inflating the price of Mango’s MNGO token by over 1,300% in a matter of minutes and using the resulting gains as collatera…

    Will Bitcoin bulls secure $110K before BTC’s $13.8B options expiry?
    Key takeaways: Bitcoin bulls aim to push BTC above $110,000 by May 30 to capitalize on $4.8 billion in call options. Spot BTC ETF inflows and weak put positioning give bulls a strong edge in the monthly expiry. Bitcoin (BTC) is approaching its largest monthly options expiry of 2025, with total exposure reaching $13.8 billion. This event gives bulls a chance to secure Bitcoin’s price above $110,000, as bears were caught off guard by a 25% rally over the past 30 days. May 30 Bitcoin options open interest, USD. Source: Laevitas.ch The open interest in Bitcoin put (sell) options stands at $6.5 billion, but 95% of these positions are set below $109,000. Therefore, if Bitcoin’s price holds near current levels, less than $350 million worth of put options will remain relevant at expiry. Convers…

    Pipelining for Memcached
    Typical Client-Server protocols operate a request - response model. With the HTTP1 protocol for example, Request N+1 is blocked by Request N on a single TCP connection. With clients like web browsers, the workaround is to establish a pool of connections which allow multiple assets like images, scripts to be requested all at once. This means that requests N and N+1 could be sent all at once. Pipelining was eventually implemented in HTTP1.1, which allows multiple requests to be sent over the same connection without waiting for the server's response. Even with this solution, The requests must still be processed in order. This is the head of line (HOL) blocking problem, where the processing of these requests are still as fast as the slowest request. HTTP2 solved this with multiplexing. Multi…  ( 6 min )

    Why AI struggles with "no" and what that teaches us about ourselves
    Over the last few months, I’ve been building some pretty layered automation using Zapier, Ghost, PDFMonkey, and Cloudinary, guided step by step by ChatGPT, and it’s been... eye-opening. I think AI is the best assistant ever when exploring possibilities to solve a problem, but it occasionally fails in ways that feel surprisingly human. As a former teacher, I’ve come to appreciate two patterns—two things large language models consistently struggle with—that have deep roots in how people think and learn. Let’s break them down. One of the most common mistakes I’ve seen ChatGPT make is with “negative commands.” For example, I once said: “Don’t overwrite existing tags unless the user doesn’t have any.” The result? The tag was overwritten, even when it shouldn’t have been. Why? Because large lan…  ( 6 min )
    Forged in Silence: Building Sigil Without an Audience

Mutations that leave a trace. Systems that can explain why they did what they did—because that’s the point. And I’ve been doing it solo. Most days, I’m on it constantly. Reading. Writing. Designing. Debugging. Thinking five moves ahead and five years back. But as of May 19th, I haven’t touched a single line of new code. Not because I burned out. Not because I hit a wall. But because after weeks of pushing this out—blog posts, GitHub, Reddit, YouTube—there’s ju…  ( 4 min )

    IEnumerable vs IReadOnlyList in .NET: When Should You Use Each?
    If you’re working in C# and .NET, you’ll quickly run into different collection interfaces like IEnumerable and IReadOnlyList.

In this post, I’ll break down the differences, show real-world use cases, and give you code samples so you know exactly when to reach for one or the other. IEnumerable The simplest way to represent a sequence of items that you can iterate over (with foreach). It doesn’t let you access by index or get the count directly. IReadOnlyList Represents a read-only list of items. You can access items by index and get the number of items, but you can’t change the collection.

In this post, I'll help demystify lifetimes by breaking them down into simple, digestible concepts. We'll use a real-world analogy to make it stick, build up from an easy code example, and explore how lifetimes help Rust ensure memory safety.

So I asked: What happens if we remove all communication and pretend that’s an upgrade? “The OS of Nonverbal Presence.” Whispr is a fully silent productivity platform. The branding is pure Silicon Valley: Jargonized fake metrics ✅ Monospace font and sacred geometry ✅ A tagline that feels like it could be AI-generated or Buddhist ✅ 🔗 You can experience the void here People started asking for the SDK. One VC asked if it was invite-only. A designer offered to “collab on the brand strategy of the void.” The fun part? believable it became. Modern dev culture has over-optimized for: Articulating ideas Framing narratives Over-documenting “value” We don’t build products. performance rituals of doing work. Whispr isn’t satire — it’s just... slightly ahead. Whispr exposes how much of work is social positioning: Saying “let’s circle back” instead of “I don’t know” Writing strategy docs that no one reads Designing decks to impress other decks Silence removed all that. Good satire should feel plausible to those it mocks. Tech loves mysticism when it’s dressed in metrics. If you make your BS beautiful enough, someone will fund it. Whispr was never about silence. techno-rituals we mistake for clarity. In pretending to launch a joke, I accidentally diagnosed a condition. “Whispr changed nothing. That was the point.” — Me, probably mid-existential crisis, but silently.  ( 4 min )
    AI's Human Horizon
    Artificial intelligence is no longer a futuristic dream—it's quietly woven itself into every aspect of our lives. From healthcare diagnoses to music recommendations, from shopping habits to social connections, AI orchestrates our everyday experiences, shaping personal choices and broader societal outcomes. But there's a crucial caveat: are we becoming masters of this remarkable technology, or servants to its silent power? We're at a defining crossroads. The ethical compass we calibrate today determines the AI-driven world we wake up to tomorrow. Beyond the allure of machines and codes, technology carries a deeply human responsibility. It challenges us profoundly—asking us how we'll protect freedom, ensure fairness, and preserve dignity in an AI-infused world. Every digital step leaves foot…  ( 6 min )
    Interactive Map
    Lots of features have been added since the last blog post. The addition of an interactive map is the biggest game-changer. The map is based on the Leaflet module, which is entirely open-source and free. It can pull imagery from any source, so I chose OpenStreetMap, since it is also free. In order to give visitors a true-to-scale overview of the farm's layout, I overlayed markers, zones, and paths on the map based on real coordinates. Most icons are stored on the server as SVGs, and then processed through a custom "icon factory" when they are needed. This makes it easy to add new icons, and reuse existing ones. The map has been made interactive by allowing certain elements to be clicked on, which will reveal a 'popup' with more content. Utilizing the JS navigator.geolocation API, I implemented a simple geolocation feature that refreshes every 8 seconds. Users can click the GPS button to center the map on their location. In order to reduce crowding and maintain the aesthetic appeal of the map, some icons and tooltips will disappear when zoomed out to certain levels. Additionally, zooming has been limited to level 16, and capped at level 19, since that is the maximum level OpenStreetMap will provide tiles for. This feature fully incorporates the map with the rest of the website. I've made a lightweight system that allows linking to specific coordinates via the URL query. This will enable visitors to be pointed directly to the location they're looking for without pouring over the map.  ( 3 min )

    Tailwind CSS: The Utility-First Revolution in Frontend Development
    Frontend development has undergone significant changes in styling approaches. While methodologies like BEM and preprocessors like Sass previously dominated, today more and more teams are transitioning to the utility-first approach embodied in Tailwind CSS. This framework has fundamentally changed the perception of how CSS architecture should look in modern applications. Tailwind CSS is a utility-first CSS framework that provides a set of low-level utility classes for building custom user interfaces. Unlike component frameworks like Bootstrap or Bulma, Tailwind doesn't offer ready-made components but provides tools for creating them. The core philosophy of Tailwind is that instead of writing custom CSS, you combine small, reusable utility classes directly in your HTML markup. <!-- Tradition…  ( 5 min )

    # 🧩 nodeBond: Lightweight IPC for Node.js — revived and improved
    "Modern inter-process communication made simple. A refreshed IPC bus for local Node.js microservices." Hi everyone! Have you ever had to connect several Node.js processes running on the same machine? Maybe you're splitting a monolith into smaller pieces, running worker daemons, or coordinating local tools? Standard solutions like child_process, stdin/stdout, named pipes or TCP — they all work, but come with tons of boilerplate: serialization, routing, discovery, and error handling. This is where nodeBond comes in — a revived and redesigned lightweight IPC bus for local Node.js services. Yes, it’s an old idea — now completely reworked and updated in version 4.0.0 ✨ Setting up raw sockets is error-prone No built-in service discovery No shared in-memory state (without adding Redis or DB) Ha…  ( 4 min )

    AI Trap for programmers beginners
    Hi, I'm Edith, this is my first post here and i just wanted to talk about something that has been bothering me, which is how AI usage is such a trap for beginner programmers. I'm giving my first hand experience. Apologies if its not all that i will get better at this with practice Okay, let me give you a scenario, you are a beginner programmer (like me) and you really wanna grasp concepts as soon as possible This was my toughest pill to swallow I wont lie haha... most of us who have passion for programming fail to acknowledge that its not as easy as we thought. You are learning a new language and this requires an identity shift which is the hardest thing to do especially if you are someone like me. You need to change how you think and approach problems. https://youtu.be/2-ePXrJZ5Oo?si=ouIXR1UZbwu1gRo_ As programmers the most important thing is learning from YOUR mistakes no matter how tedious. Understand your code and master the logic behind it and before anything make sure you think like a programmer; breakdown your problems and find logical solutions to them. In the long term you will be proud of yourself and your future self will thank you for enduring. ദ്ദി ≽^⎚˕⎚^≼ .ᐟ ദ്ദി๑>؂•̀๑) ( ദ്ദി ˙ᗜ˙ ) THANKS FOR READING  ( 4 min )
    How to Quickly Identify the Cause When You Can't Eject a Disk on Mac (Bite-size Article)
    Introduction Today's post will be quite short, but I’m writing it down as a personal memo. I often use my DSLR for work, and after every shoot, I insert the SD card into my Mac to transfer the data. This error always appears when I press the eject button for the disk in Finder. Of course, I always ensure that the data transfer to the Mac is complete before attempting to eject, so there should be no procedural issues. Nevertheless, I never understood the cause and had been force ejecting the disk every time. But of course, this is not a good practice, and depending on the situation, it could potentially lead to disk damage, malfunction, or even data loss. Allowing such risky operations to become a habit is not ideal. lsof Command I decided to look into the issue a bit more today and f…  ( 5 min )

    Automatically Map Workouts to the Right Apple HealthKit Type -HKWorkoutActivityType
    Introduction If you've ever tried integrating Apple HealthKit into your fitness app, you've probably faced this frustrating step: "Which HKWorkoutActivityType should I use for this workout?" Choosing the wrong type means poor sensor activation (or none), inaccurate data, and a worse user experience. Apps get bad reviews because of this — especially if the user just paid $400 for their new Apple Watch. In this tutorial, I'll walk you through how to automatically classify any workout to its correct HKWorkoutActivityType using Fit2Apple. Fit2Apple is an API that uses a research-backed 4-stage pipeline to classify and score workouts based on exercise names, sets, durations, rest, and intensity. Whether you're using standard workouts or custom routines from your app, this saves you hours of …  ( 5 min )
    Transient Activation: Why the copy button did not work on iPhone

If you're aware of Safari's quirky ways with the Clipboard API, feel free to skip. Otherwise carry on, this write-up might save you some time in the future. Let's set the scene. We'd introduced a handy modal where users could update a setting and then instantly copy a generated link. Think Google Sheets' share functionality: you tweak sharing permissions, then grab the link. Our process was straightforward: A server call to update the setting. A copy operation to grab the shiny new link.

    5 Fundamental Principles of Networking That Connect Two Computers
    Computer networks are the backbone of digital communication. Even a simple connection between two computers involves several crucial principles to ensure seamless and secure data exchange. In this article, we’ll explore five fundamental networking principles every beginner should understand. Communication Protocols A protocol is a set of rules that define how data is transmitted and received across a network. For two computers to communicate, they must speak the same "language"—typically TCP/IP (Transmission Control Protocol/Internet Protocol). 🔍 Example: TCP handles the breakdown and reconstruction of data packets, while IP manages the addressing and routing of data to the right destination.

Part 4: Manage Services Like a Sysadmin Ninja Part 5: Bonus Scripting Practice Final Words of Wisdom You’ve fired up your RHEL 9 VM, flexed your typing fingers, and bravely typed lsblk… only to be ghosted by /dev/sdb. But guess what? You’re still in the game. And this guide is for you — the Linux warrior who keeps going, one command at a time. If you tried lsblk and /dev/sdb is still in hiding, it's okay. You can still practice tons of RHCSA skills using the space and partitions you already have. Let’s pivot to the real-world RHCSA tactics you can conquer right now: Make your own top-secret coffee log: This is the command line equivalent of putting your diary under lock and key. Because every RHCSA candidate should know how to create a user who respects a properly brewed cup of the sweet bean juice. Create a loopback device — it's like a pretend disk: I'll admit, this was a hard one to grasp but perseverance and hard work paid off! I debated whether to keep my mistakes in and re-do it to make it look clear, but sometimes, we need to own our mistakes and embrace them, that's how we learn, and grow. Boom. Fake disk. Real experience. Zero stress. Learn to control services. Become the puppet master of your system. Create a basic shell script because scripts are sexy and RHCSA loves them: Save it as brew.sh, make it executable. Boom. You just automated a task. Hire yourself. Don’t let hardware hiccups stop your hustle. The RHCSA is as much about mindset as it is about commands. You’re learning. You’re practicing. And that’s more powerful than a second disk. Need help fixing VirtualBox or creating more real-world practice scenarios with what you have? I’ve got you. Just say the word.  ( 4 min )

La investigación en IA comenzó en los años 40 del siglo XX. aunque el término IA no se acuñaría hasta 1956. El trabajo se centraría en la creación de máquinas inteligentes. Lo primero que se debatió fue... ¿qué es la inteligencia? ¿cómo puede definirse? Como no se llegó a ningún acuerdo o avance sobre este tema, Alan Turing crea su famoso Test de Turing.

In this overview, we’ll explore the purpose, mechanics and typical use cases of IP, TCP, UDP and HTTP—all in a succinct, professional format. IP (Internet Protocol) IP provides logical addressing and packet routing across interconnected networks. Every device on the network is assigned an IP address (IPv4 or IPv6), which uniquely identifies its location. How It Works Packetization: Data is broken into discrete units called packets. Addressing: Each packet header contains source and destination IP addresses. Routing: Routers examine destination addresses and forward packets toward their target, potentially across multiple networks. Unreliable Delivery: IP makes no guarantees about packet delivery, order or duplicati…  ( 4 min )

    Blazor and validation In the previous post we took a look at setting up validation, using Data Annotations and IValidatableObject. In this blog we will take a look at how we can use this validation in a Blazor project. We will define a few rules/requirements to make the sample more clear: We will be simulating a real database, but we will not set up a real connection. We will not take into account security. We will disable prerendering for our Blazor application. Prerendering causes additional headaches for our pages, which are really out of scope for this blog post! Our domain is pretty simple! We will have a list of users, which we can retrieve and create! A user will look like so: [Index(nameof(Email), IsUnique = true)] public class User { [DatabaseGenerated(DatabaseGeneratedOptio…  ( 8 min )
    A Beginner's Guide to Getting Started with Multimodality in LangChain
    AI models are becoming increasingly adept at processing data beyond just text. They can now take in images, audio, video, and even documents like PDFs. This ability to handle multiple types of input is known as multimodality, and it's starting to shape how developers build smarter, more flexible systems. In LangChain, multimodality is beginning to show up in different parts of the stack, from chat models that can describe images to embedding models that could one day support audio or video search. It’s still early, and the tooling isn’t fully standardized, but support is growing fast. So, here’s the exciting thing: We are currently working on Langcasts.com, a resource crafted specifically for AI engineers, whether you're just getting started or already deep in the game.

    The Decline of Code Memory
    The Decline of Code Memory (and Why It Matters More Than You Think) How many times have you checked the React docs for the same useEffect example this month? Or maybe you just prompt your AI assistant and vibe your way through the code. Today, many developers rely less on memorizing syntax and more on tools that help complete or generate code quickly. That convenience comes at a cost: we’re gradually losing the ability to remember the code we write every day—and that matters more than you might think. Modern development has changed. We no longer need to memorize syntax, so we don’t. Instead, we search/prompt. We copy. We paste. Sometimes we don’t even understand the code we’re running—just that it works. This isn’t entirely bad; tools are meant to boost us. But there’s a hidden cost. We…  ( 4 min )

    How to fix CORS errors in Node.js
    8 Common CORS Errors in Web Development (and How to Fix Them in Node.js) Cross-Origin Resource Sharing (CORS) errors are among the most frequent and frustrating issues in modern web development.

I know that people have said that AI can help you with programming and I thought I’d see how much help it was getting me unstuck. I went a few rounds with it coming up with suggestion that sounded reasonable, but none of them helped. Although I found that telling it exactly what wasn’t working helped me to establish what the problem actually was. Sadly, though, it then started giving me code where I couldn’t see what it had changed. When I asked, it told me it had added a function.

    The Power of Boring Tech: Why Simple Tools Often Win
    “Choose boring technology.” — Dan McKinley (ex-Engineering at Etsy) In the age of constant innovation and shiny new frameworks, it’s tempting to jump on every new tool that promises to change your dev life. But sometimes, the best tool is the one you don’t notice—because it just works. Welcome to the case for boring tech. Boring tech isn't bad tech. It's well-established, stable, and widely understood. It’s PostgreSQL over some NoSQL flavor-of-the-month. It’s Rails or Django over the latest JS meta-framework. It’s SSH and cron instead of a complex CI/CD toolchain you don’t understand. Boring tech has survived years of production use. It has documentation, Stack Overflow threads, GitHub issues, and real-world success stories. Good luck finding a dev fluent in a 3-month-old build tool. With boring tech, there’s a bigger talent pool and faster onboarding. Shiny tools break. APIs change. Dependencies rot. Boring tech? It’s predictable—and predictability is a superpower in production. 🐘 PostgreSQL 🧱 jQuery (yes, still!) 📦 Docker 🐍 Python 🛠 Bash scripts 🔧 cron jobs 🧑‍💻 Git None of these make headlines—but they keep the digital world running. Of course, boring tech isn’t always the answer. Use cutting-edge tools when: Your problem is novel or evolving fast You're prototyping and optimizing later You want to experiment (and accept the risks) But in production? Simplicity scales. Tech isn’t about what’s coolest—it’s about what delivers reliably. If you want to ship, sleep, and scale, maybe it’s time to go back to basics. 🖋 Written by Juan G., builder of useful things and fan of predictable systems.  ( 3 min )

    Query Strings vs. Hash Fragments: What’s the Real Difference?

    Unraveling the Chain: A Deep Dive into Linked Lists 🔗
    Understanding Linked Lists in Computer Science Linked lists are a fundamental data structure in computer science, forming the backbone of many complex systems and algorithms. Understanding them is crucial for any aspiring programmer or software engineer. This article will explore the different types of linked lists, their uses, historical significance, advantages, drawbacks, and why they remain incredibly relevant today. At its core, a linked list is a linear collection of data elements, called nodes. Unlike arrays, where elements are stored in contiguous memory locations, linked list nodes can be scattered anywhere in memory. Each node contains two key pieces of information: Data: The actual value stored in the node (e.g., a number, a string, or a more complex object). Pointer (or Link)…  ( 8 min )
    Understanding NodeList in JavaScript
    When working with the Document Object Model (DOM) in JavaScript, one often encounters collections of elements rather than individual ones. One such collection type is the NodeList. Understanding what a NodeList is, how it differs from similar data structures like arrays, and how to work with it effectively is essential for writing robust and efficient JavaScript code. A NodeList is a collection of nodes returned by DOM methods such as document.querySelectorAll() or Node.childNodes. It represents a list of nodes in the order they appear in the document. const items = document.querySelectorAll('.item'); console.log(items); // NodeList of elements with class 'item' In this example, items is a NodeList containing all elements with the class item.

    Make Your Terminal Beautiful with Python: ASCII Art & Fancy Progress Bars ✨🐍!!
    Want to level up your terminal output with cool animations, progress bars, and fancy ASCII art? This quick guide shows you how to combine three awesome Python libraries to do just that: pyfiglet — for eye-catching ASCII text banners. Why Care About Terminal Styling? When building CLI tools or scripts, output styling helps: Code Example import pyfiglet from tqdm import tqdm from rich.console import Console from rich.progress import track import time # ---------- 1. ASCII Art ---------- ascii_banner = pyfiglet.figlet_format("Nishkarsh!") print(ascii_banner) # ---------- 2. TQDM Progress Bar ---------- print("\n[1] Loading with tqdm:") for _ in tqdm(range(50), desc="Loading..."): time.sleep(0.02) # ---------- 3. Rich Progress Bar ---------- console = Console() print("\n[2] Fancy Progress with Rich:") for step in track(range(10), description="Processing tasks..."): time.sleep(0.1) # ---------- 4. Rich Spinner / Status ---------- print("\n[3] Animated Spinner with Rich:") with console.status("[bold green]Finalizing magic..."): time.sleep(2) console.print("\n[bold cyan]All done! Your terminal is now beautiful. 🌈[/bold cyan]") Output: What Happens Here? tqdm shows a simple progress bar with a label "Loading..." that fills up as the loop runs. rich’s track() gives a colorful, animated progress bar with the label "Processing tasks...". rich also lets you create a spinner with a status message (Finalizing magic...) to show a task in progress. Finally, it prints a colored success message with emoji to celebrate! How to Run This pip install pyfiglet tqdm rich Save the script as terminal_magic.py python terminal_magic.py What Else Can You Do? Combine rich’s tables, trees, and markdown for killer CLI apps. Final Thoughts Adding some style to your terminal output is easier than you think — and it makes your tools so much nicer to use.

    Set Limits for Your Boss
    I have been a programmer for many years, I admit I'm no where close to the best, but I kept plugging away and did accomplish some things that made people more productive, and maybe less frustrated. Along the way I learned that I needed to set limits on my boss, whoever they were at the time. Let me explain. One time the IT director told me I had gotten a bad review from a primary stakeholder. 'Never completed a project' I thought things were going along quite well, so how did that happen? This 'primary stakeholder' was always moving the end goal, or adding to the list of functions. Therefore, I was never finishing or reaching the end. From then on I needed a protection against bad reviews. No one had told me before that I needed a contract for work accomplished. I started writing up a project plan and had the stakeholder sign off, before work started, and when completed. Then they could add or change anything they liked. Only they first needed to acknowledge that this task was completed. That put an end to bad the reviews, and made everyone happier, especially me. :-)  ( 3 min )

Tools are what transform a basic conversational agent into a truly useful assistant that can interact with the world. In this tutorial, we'll explore both built-in tools provided by the Strands SDK, and learn how to create our own custom tools. How to integrate built-in tools from the strands-agents-tools package How to create custom tools using the @tool decorator How to implement file operations for learning resources How to build a custom glossary tool for our agent Completed Part 1: Creating Your First Agent The Strands Agents SDK ins…  ( 8 min )
    TypeScript: A Comprehensive Guide for Developers
    JavaScript has long been the dominant language of the web. However, as applications have grown in complexity, developers have increasingly turned to TypeScript — a statically typed superset of JavaScript — to gain better tooling, improved readability, and fewer runtime errors. In this blog post, we’ll dive deep into TypeScript, exploring its features, benefits, and how to get started. What is TypeScript? Key Features of TypeScript Static Typing TypeScript introduces types to JavaScript. This means you can specify the type of a variable, function parameter, or return value, which helps catch type-related bugs early in the development process.

    7 Modern Use Cases of IIFE
    In the last article, I introduced the try-catch IIFE pattern. Some of you found it clever, while others couldn’t stand the syntax. And honestly? Fair. IIFE (Immediately Invoked Function Expression) can look odd at first glance. But I’m here to change your mind. IIFE isn’t just a relic of the var era, there are still many modern use cases. Here are 7 modern use cases of IIFE that go beyond legacy code and show how they can improve clarity, encapsulation, and expressiveness in your everyday code. var Era?) Before we look at modern use cases, let’s rewind a bit. IIFE stands for Immediately Invoked Function Expression. It's a function that runs right after it’s defined. Like this: (() => { console.log("Hello!"); })(); You define a function and immediately invoke it. But why go through thi…  ( 8 min )
    .Wait() or .Result on a Task in an async context
    ❗ Avoid .Wait() and .Result in Async Contexts – Here’s Why Calling .Wait() or .Result on a Task blocks the current thread until the Task completes. 🧠 Why? The result: Deadlock. public class DeadlockDemo { public static void Main() { Console.WriteLine("Starting..."); var result = GetData().Result; // ❌ This can deadlock in UI/ASP.NET Console.WriteLine($"Result: {result}"); } public static async Task GetData() { await Task.Delay(1000); // Simulate async work return "Hello from async!"; } } What happens? public class AsyncSafeDemo { public static async Task Main() { Console.WriteLine("Starting..."); var result = await GetData(); // ✅ Safe and non-blocking Console.WriteLine($"Result: {result}"); } public static async Task GetData() { await Task.Delay(1000); // Simulate async work return "Hello from async!"; } } Why this works: ❌ Avoid .Result or .Wait() in async contexts (can cause deadlocks). ✅ Use await to keep things async and non-blocking.  ( 3 min )

    Numeric comparison in CSS
    TLDR: We can test for equality, less-than and greater-than by using a combination of calc(), abs() and sign(). Others, such as Lea Verou, have written superb guides about using binary logic to perform conditions in CSS, using CSS Variables with values of 0 or 1. Until CSS supports @if and @else then we have to make do with such workarounds. Often however, we have numbers other than 0 or 1 in our CSS Variables so it would be handy if we could compare numeric values and drive logic from them. In JS we might simply write: if (a === b) { // Apply some styles } if (a > b) { // Apply some styles } but the best we could hope for in CSS right now is to set boolean variables like the following, and to use them in Binary Linear Interpolation: --isEqual: /* Some magical logic here */ --isGreaterThan: /* Some other magical logic */ Well there is a way, using calc() and the more recent abs() and sign(). Like this... --isNotEqual: sign(abs(calc(var(--a) - var(--b)))); --isEqual: calc(1 - var(--isNotEqual)); --isLessThan: sign(max(0, calc(var(--b) - var(--a)))); --isGreaterThan: sign(max(0, calc(var(--a) - var(--b)))); --isLessThanOrEqual: calc(1 - var(--isGreaterThan)); --isGreaterThanOrEqual: calc(1 - var(--isLessThan)); /* I'd welcome any suggestions for smarter ways to derive these! */ Demo on CodePen. Note: abs() and sign() have only partial browser support but they can be achieved using older syntax. At time of writing only Safari & Firefox supported them.  ( 3 min )

    Want to Stand Out as a Junior Developer? Do it MORE.
    I remember the exact moment I realized I was doing it all wrong. It was 2 AM, and I was deep in my third "Learn React in 30 Days" tutorial. My browser had seventeen tabs open with different coding courses, my notepad was filled with “best practices” I'd copied from various blogs, and my GitHub? Completely empty. I felt productive. I felt like I was learning. But I wasn't getting anywhere. Then my friend, who started coding at the same time as I did—landed his first developer job. When I asked him for his secret, his answer floored me: "I stopped watching tutorials and started building stuff. Lots of stuff. Ugly stuff. Broken stuff. But I kept building."

    My first successful LLM fine tuning
    Yesterday I told myself I would do something other than program all day, but again ended up pushing to accomplish the goal that I felt a bit obsessed over. The goal: to fine tune Mistral using my own method, in order to create a personalized lyric generation machine. I would be training it with my own lyrics as well as injecting random sequences of words. I just had to know the effect that fine-tuning would have. Would it really be able to make the kind of creative lyrics that I wanted? Base LLMs can't really generate the kind of poetry/lyrics that actual artists do in the real world. Usually they are very hard to wrangle toward being more creative. So I figured I would try an experimental fine-tuning method with Mistral to see what effect it could have.

    Templates in Next.js
    In Next.js layout.tsx is a shared UI component between routes. layout.tsx never rerenders when we navigate from one route to another. We use layout to render static elements that are not supposed to be changed. Like, the Header, Footer, etc. It means, layout keeps your component/pages or UI the same way and renders the page.tsx in it as children, if you want. layout and template Just like layout template also wraps the pages and components as children. But the main difference between layout and template is, layout can keep the current state, but template can't. That's why layout does not change the UI or does not manipulate the DOM. On the other hand, template does not hold the state value. It changes the state rerenders the UI, and manipulates the DOM. Creating a template is very simple. Create a file named template.tsx/jsx/js.. in your desired directory. In the template, returning a React component is compulsory. Do as you do in layout.tsx import SignUp from './signup'; export default function MyTemplate({ children }: { children: React.ReactNode }) { return ( {children} ); } In summary, don't use template for static assets. Use it for where state needs to be changed and rerender the component. 'use client' Sometimes you may need to use 'use client'. When you use any React hook or state (useState, useEffect) in your template Attaches event handlers or relies on browser APIs (window, document) Imports other Client Components (e.g., a carousel, chart, or provider) Once "use client" is present, all imports become part of the client bundle.  ( 3 min )

    🚀 From Frustration to Flow: How I Finally Mastered Debugging Like a Pro
    “It’s not a bug, it’s an undocumented feature.” Every dev, at some point. Let’s face it. Debugging sucks especially when it’s 2 AM and the console is taunting you with cryptic errors. For years, I treated debugging like a necessary evil until I flipped the script. This post is about how I went from rage-quitting over bugs to actually enjoying the debugging process, and how you can do it too. Whether you're a junior dev, a bootcamp student, or a senior drowning in legacy code this is for you. A while ago, I spent 6 hours fixing a 6-line bug. Sound familiar? The turning point came during a code review. A senior dev casually said: “Don’t debug by guessing. Debug by isolating.” That sentence changed everything. Reproduce It Read the Error (Slowly) Add Minimal Logs Isolate and Comment Out Rubber Duck It 🧠 Tools That Took My Debugging to the Next Level React DevTools / Redux DevTools Network Tab in DevTools (Underrated!) Postman / Insomnia for API Isolation TypeScript + ESLint for early catches ✅ Bonus: My Debug Checklist (Save This) What was the last change before this started? Are all environment variables correct? Are third-party APIs/services up? Is this bug UI-related, logic-related, or data-related? Debugging isn’t just a skill. It’s a superpower that 10x’s your dev career. I now treat bugs as treasure maps each one leads to deeper understanding of the codebase. What’s your worst (or funniest) bug story? What’s one debugging trick you swear by? 👇 Drop it in the comments I’m reading every one.  ( 3 min )

And when I look at maintain, I get main Thema. So I’ve started calling this phenomenon “word-jamming,” Here’s a handful of jamming pairs I’ve had to wrestle with. If you’re a native English speaker, this might make zero sense. { "behavioral": ["behind"], "particularly": ["party", "patient"], "increasing": ["include"], "fidelity": ["modify"], "maintain": ["main Thema"], "rely": ["reply"], "embedded": ["embalming"], "determine": ["data mining"], "consistency": ["coexistence"], "reflect": ["reframing", "relief"], "appropriate": ["apologize", "appreciate"] } In Japanese, there’s an idea that “to understand” means “to divide.” Maybe vocabulary is like that too.

    Monitoring, Logging, and Observability in DevOps
    In today’s fast-paced software development landscape, releasing code is only half the battle. Ensuring it runs reliably in production is where DevOps practices shine. A cornerstone of maintaining resilient systems is having a solid strategy for monitoring, logging, and observability. But what do these terms actually mean, and how do they fit together in a DevOps workflow? Let’s break it down and explore some tools and practices you can start using today. Understanding the Concepts Goal:-Detect and respond to system issues before users notice them. Tools to consider: Prometheus Logging: Goal:- Debug and trace problems with context-rich, searchable logs. Best practices: Tools to consider: Observability: Goal:- Empower teams to ask questions about system behavior and get answers—without deploying new code. Three pillars of observability: Metrics – Quantitative data (CPU, memory, latency). Tools to consider: OpenTelemetry (vendor-neutral standard) Putting It All Together workflow: -Instrument your code and infrastructure with OpenTelemetry or custom metrics. -Set up log collection and aggregation with tools like Fluentd and ELK. -Build dashboards and alerts in Prometheus + Grafana. -Enable tracing for microservices using Jaeger or Zipkin. -Continuously improve your alert thresholds and monitoring queries based on incidents and postmortems. N/B: You can monitor a system without truly understanding its inner workings. Observability closes that gap. Final Thoughts What tools and practices do you use for observability?

    How to add markdown to a Next.js project
    Markdown Markdown is a standardised way of writing documents to include formatting like headers, italics, bold, list, links, etc. Normally, there is not a mechanism within frameworks to directly translate markdown into rendered HTML. This guide may help you add this functionality to a Next.js project should you wish, like us, to add blogs to your site. Markdown itself is a lightweight markup language. You won't normally see the untranslated raw code, unless you are perhaps a Content Creator. You will normally see the rendered HTML result in a browser. An example of markdown might look like this: ## This is a header **This is bold** _And this is italic_ [I am a link](https://futools.online) - [ ] Task List Item 1 - [ ] Task List Item 2 - [ ] Task List Item 3 Which will render to this…  ( 6 min )

    The future of passwords is bright
    I see the future. I see it so clearly that you will receive this in a few years. Dear Customer, The BlahBlah monitoring system has noticed suspicious attempts to log in to multiple users’ accounts (an AI brute-force technique). Your account has been recognized with potentially weak security settings. Therefore, to prevent unauthorized access, your account password has been regenerated automatically. To restore access and ensure the security of your account, please complete the following step: Reset a new strong password(At least 58 characters, including at least 3 uppercase, 7 lowercase letters, 9 numbers, and at least 7 special characters, e.g., ! @ # ? ]) Your future BlahBlah security team Why?

    Beyond the Border: How Pakistan's Trilateral Reset Redefined Regional Power
    In the great geopolitical theatre of South Asia, Pakistan was often cast as the reactive actor — defending, surviving, recalibrating. But that script has been rewritten. Not through war, but through diplomacy, deterrence, and doctrine. India’s two-front war fantasy — engaging China in the north while destabilizing Pakistan in the west — was never a strategy rooted in reality. It was a media script designed to boost morale, push military spending, and sell the illusion of supremacy. That illusion fell apart in 2025. China’s decisive diplomatic entrance into Afghanistan, coupled with Pakistan’s security synchronization with the Taliban regime, ended India’s covert playground. RAW’s logistical networks, once thriving in Kandahar and Jalalabad, have dried up. And with the collapse of those cor…  ( 4 min )
    La Trampa de la Sobre-Normalización
    Introducción: El Equilibrio Perdido en el Diseño de Bases de Datos En el mundo del diseño de bases de datos relacionales, existe una tendencia casi religiosa hacia la normalización perfecta. Los diseñadores novatos, armados con las reglas de Codd y la teoría relacional, se embarcan en cruzadas para eliminar cada vestigio de redundancia. Sin embargo, esta búsqueda obsesiva de la pureza teórica puede convertirse en una trampa que compromete gravemente el rendimiento, la mantenibilidad y la usabilidad práctica de los sistemas de bases de datos.

    Why Did Google Change Its Logo After Decades?
    You may have noticed that Google’s logo today is flat, colorful, and minimal — a big shift from the old serif-style version we saw in the early 2000s. But why the change? When Did Google Change Its Logo? Google last changed its logo on September 1, 2015. The previous version used a serif font with a more traditional look. The new logo features a sans-serif font, brighter colors, and a design optimized for digital platforms. Old Tech, Old Challenges Back then, CRT monitors didn’t show colors accurately, and early printers couldn’t match on-screen colors well. So, logos were kept simple, with basic colors and solid shapes to avoid issues in print and digital formats. Now Everything’s Digital Today, screens are high-resolution, color-accurate, and mobile-friendly. Printing tech has also caught up. Most importantly, our lives are now digital-first — so logos need to look great on screens of all sizes. Google’s 2015 logo update introduced a clean, modern, and scalable design. It’s easy to read, works across devices, and feels more playful and user-friendly — just like Google's services. What Do You Think? This is just my opinion based on how technology has evolved. But what about you?Do you think there’s another reason Google changed its logo?It feels like many brands are updating their logos these days — maybe Google just joined the trend too.  ( 3 min )

    Why You Should Use MVC Architecture in Express.js for Scalable Web Apps
    If you’re diving into building web applications with Express.js, you’ve probably heard about the MVC (Model-View-Controller) architecture. But why is MVC such a popular choice among developers? And how can it supercharge your Express.js projects? In this blog, I’ll walk you through the usefulness, advantages, and scalability of MVC in Express.js, sprinkle in some fun facts, and give you actionable insights to start implementing it today. MVC is a design pattern that divides your application into three interconnected components: Model: Manages data and business logic View: Handles the user interface and presentation Controller: Acts as an intermediary, processing user input and interacting with Models and Views This separation helps keep your code organized, maintainable, and scalable.

    I built open-source app to stop micromanaging my finance
    Throughout my life, I've tried to get on top of my finances and understand my financial performance. I experimented with numerous finance tracker apps, but none of them truly worked for me. The main issue was their demand for regular input—logging expenses, scanning receipts, categorizing transactions, and tracking goals. This felt like a burden, and I soon realized that I don't need to micromanage my transactions. It's pointless for me to know if this week's spending is higher than last week's, or if I spent more on clothes this month than usual. What I truly want is a high-level overview of my savings. Did my wealth increase over the year? Is it worthwhile to diversify savings between CNY and USD? What's the total of my savings spread across several banks, brokers, and crypto-wallets?

Your tests must simulate edge cases carefully to avoid unintended consequences on live networks. Distributed Consensus – Bugs in c…  ( 4 min )
    Polyfill for CSS sign()
    CSS sign() is not well supported but can be 'polyfilled' with calc & clamp: --input: 10; /* <-- Any number */ --num: calc(var(--input) * infinity); --sign: clamp(-1, var(--num), 1); Handy if you're attempting conditional logic and you need 0's and 1's instead of numbers. (What? Why? Read more about Binary Linear Interpolation). How it works: Multiply by infinity to give us 0 or +/- infinity to avoid rounding errors when dealing with very small decimals. Tip: If you know your input numbers will never be between -1 and 1 then you can skip the calc(). Round to the nearest -1, 0 or 1. Demo on CodePen:  ( 3 min )

    What Is Cybersecurity, Really? Separating Myth from Reality
    By [Lawson Peters] | Cybersecurity Analyst & Cloud Enthusiast Cybersecurity protects digital systems from attacks, not just hacking, and is crucial for everyone. It seems likely that common myths, like only techies need it, can leave individuals and businesses vulnerable. Research suggests small businesses and individuals are often targets, not just big corporations. The evidence leans toward needing more than strong passwords, like two-factor authentication, for safety. Recent attacks, such as the 2025 Morocco data breach, show the real-world impact of cybersecurity failures. Cybersecurity is about keeping your digital life safe, like locking your doors at home. It protects systems, networks, and programs from attacks that can steal data, demand money, or disrupt services. Think of it as …  ( 8 min )

    Learning CSS Colors Shouldn’t Be This Fun (But Here We Are)
    Let me tell you a secret—I used to think CSS colors were boring. "Oh wow, hex codes, how thrilling," I’d say, rolling my eyes so hard I could see my own brain. But then I built this Ultimate CSS Colors Tool (Pro Edition™) and—plot twist—it turns out colors are actually kinda dope? Why This Tool is Different (And Why You’ll Actually Learn Stuff) Most color tutorials are like: "Here’s HEX, RGB, and HSL." "Good luck figuring out the rest, loser." Meanwhile, this tool is like: "Here’s HEX, RGB, HSL, HSLA, HWB, OKLab, OKLCH, Display-P3, and even CMYK (for some reason)." "Oh, you wanna play with sliders and see real-time changes? Say less." "Want to copy-paste code like a pro? Done." What You Get: ✅ All Color Formats Explained – From basic HEX to futuristic OKLCH. ✅ Interactive Playground – Because reading is hard, but clicking is fun. ✅ Real-World Use Cases – See how colors work in actual CSS (not just theory). ✅ Pre-Made Palettes – Tailwind, Material Design, Flat UI—steal them. I won’t tell. ✅ Copy-Paste Magic – One-click CSS snippets because we’re lazy geniuses. The Best Part? It’s Actually Useful You know those tutorials that teach you something and then you immediately forget it? Yeah, this ain’t that. Learn by doing (sliders! buttons! shiny things!) See contrast ratios (so you don’t blind your users) Export your colors (because memorizing hex codes is for psychopaths) Try It Yourself (Or Don’t, I’m Not Your Boss) If you’ve ever: Googled "CSS color formats" and got a 10-year-old blog post Struggled with HSL like it’s some kind of math test Wanted to use modern color spaces but had no idea how …then this tool is for you. 👉 [Check it out here] (or just stare at the pretty colors, I don’t judge). Final Thought: CSS colors don’t have to suck. This tool makes them almost fun. And if it doesn’t? Well, at least you got to play with sliders. Happy coloring! 🎨  ( 3 min )

    Java vs. Kotlin: Which One Should You Learn for Backend Development?
    When deciding between Java and Kotlin for backend development, understanding their key strengths is essential. Java has long been the industry standard for building robust, scalable backend systems with a vast ecosystem and mature frameworks like Spring Boot. It offers excellent performance, strong community support, and extensive libraries, making it a reliable choice for enterprise applications. On the other hand, Kotlin is rapidly gaining popularity for backend development due to its concise syntax, null safety features, and seamless interoperability with Java. Kotlin’s modern language design reduces boilerplate code, which speeds up development and improves code maintainability. It also supports coroutines, enabling efficient asynchronous programming that’s perfect for building high-performance backend services. Both languages integrate well with popular tools and cloud platforms, but Kotlin is often preferred in new projects looking for modern solutions, while Java remains dominant in legacy systems and large-scale applications. Ultimately, your choice should consider factors like project requirements, team expertise, and future scalability. Staying updated with current trends, frameworks, and cloud-native development can help you make the best decision for backend programming in 2024.  ( 3 min )

    When “Leadership” Becomes Abuse in Disguise
    Lately, I’ve been seeing stories that genuinely shock me - managers deliberately sabotaging production, creating chaos, or manipulating deadlines just to see how their devs react under pressure. Let’s be clear: this isn’t leadership. This is abuse. You don’t build trust or resilience by throwing your team into trauma scenarios. You don’t foster collaboration by making people suffer. And you definitely don’t promote “team skills” by manufacturing stress. That’s not psychological safety - that’s psychological warfare. If this happened in any other field - construction, demolition, food service - the manager would be gone. Immediately. Because putting people at risk for the sake of your curiosity or ego is unacceptable. Just because developers work at desks doesn’t mean they aren’t affected. Burnout is real. Mental exhaustion is real. People leave not because they’re weak - but because they’re being used as stress test dummies. You don’t test loyalty by creating chaos. You earn it by creating clarity. You don’t build team skills through sabotage. You build them through support. We need to stop celebrating toxic “leadership” and start holding it accountable.

    The research unequivocally demonstrates that TFAP2C warrants consideration as a valuable biomarker for the prevention and treatment of psoriasis. Estimated to affect 21 to 67% of children and adolescents, urticaria is a common disorder, which commonly necessitates emergency department admissions. In the atopic condition known as allergic rhinitis (AR), the immune system's response to environmental factors manifests as clinical symptoms. Helicobacter pylori's neutrophil-activating protein (HP-NAP), a peptide, acts to reduce Th2 responses and encourage Th1 activity; the mucus-binding cell-surface protein MapA binds to mucosal lining. This study investigated the impact of HP-NAP and MapA, when combined with alumina nanoparticles, on the expression of AR. Alumina nanoparticles were conjugate…  ( 7 min )

    Your Computer Sucks? Blame Your Weak Will (and Maybe Hanish)
    Let's be real, guys. Nothing grinds our gears more than tech that can't keep up. You're trying to crush the competition in that game, or maybe just trying to watch the highlights without buffering every two seconds, and BAM! Frozen screen. You feel that primal rage building, right? That's your inner caveman screaming for efficiency. And if you're anything like my buddy Hanish, his inner caveman goes full berserker. Dude once headbutted his router because Netflix was lagging. True story. Now, some egghead philosopher named Nietzsche (don't worry, I can barely pronounce it either) had this idea about the "will to power." Basically, it's the manly urge to get better, to dominate challenges, and to generally be more awesome. Think about hitting the gym and pushing yourself to lift more – that'…  ( 4 min )

    Enhancing QR Codes in the Age of GenAI
    Traditional QR Codes Quick Response (QR) codes were developed in 1994 by Masahiro Hara and are now recognized as an ISO/IEC standard. They represent an evolution of 2D barcodes, capable of encoding numeric, alphanumeric, binary, or Kanji data in the form of a pattern of black squares on a white background. These codes are available in various sizes (or versions), ranging from version 1 (21 x 21 squares) to version 40 (177 x 177 squares). Numerous libraries and tools exist for generating QR codes. My preferred open-source library is QR Code Generator, which supports all standard features and is available in Java, TypeScript/JavaScript, Python, Rust, C++, and C.

    Graph Databases Are Not Just for Social Networks
    Graph databases have long been synonymous with social media platforms—Facebook, LinkedIn, Twitter. But what if I told you they’re powering much more than just your friend lists and follower graphs? In this post, I’ll show you why graph databases are becoming mission-critical for industries like cybersecurity, fraud detection, recommendation engines, and even SEO—and how you can start using them today. Traditional relational databases are amazing—for structured, tabular data. But as soon as relationships become complex and interconnected, they fall short. Enter graph databases.

    SQL vs NoSQL? Why Not Both?
    For years, developers have heard the whispers: “SQL is outdated. NoSQL is the future.” But here's the truth — SQL is not dead. It's evolving. And it’s more powerful than ever. The rise of hybrid databases is reshaping how we build scalable, high-performance apps. SQL has long been the default choice for structured data and relational integrity. Then came NoSQL, offering flexibility and scalability at the cost of relationships and consistency. But in today’s fast-paced development world, why settle for just one?

    How Refining Fees Are Calculated and What You’re Really Paying For
    Whether you're a jeweler reclaiming karat scrap, a recycler processing e-waste, or a miner producing dore bars, refining fees directly impact your bottom line. These fees determine how much payout you receive for your material—and, in many cases, whether the transaction is profitable at all. Understanding how refining charges are structured is critical to: Accurately pricing your metal output or scrap intake Negotiating better contract terms with refineries Preventing unexpected deductions or hidden costs In a market where margins can be razor-thin, every ounce and every basis point counts. Refining is the process of converting impure or mixed-metal material into high-purity bullion that meets market or exchange standards.

    PostgreSQL (with JSONB) and MongoDB (with schema)
    In recent years, MongoDB and PostgreSQL have gained popularity, representing the NoSQL and SQL camps, respectively. Each technology is optimized for different data modeling approaches: PostgreSQL serves as a general-purpose relational database, while MongoDB functions as a general-purpose document database. While one is more data-centric and the other more application-centric, both can handle similar workloads. PostgreSQL offers flexibility over relational with its JSONB datatype, and MongoDB's flexible schema allows for some normalization through references and schema validation. However, designing a document database as a relational one is inefficient, and vice versa. Although PostgreSQL can superficially resemble a document database with JSON datatypes, it is not optimized for using it …  ( 3 min )

    How to Find and Fix Common Bottlenecks in Business Workflows
    Operational issues don’t usually appear overnight – they tend to build up slowly, gradually affecting how efficiently processes run. Many companies, no matter their size or industry, experience similar challenges. Let’s take a look at some of the most common ones below. Manual processes Many businesses rely on manual tasks, especially during their early growth stages. But as data and customer numbers increase, routine work takes up more time. This can lead to employee overload and slower response times. Instead of progressing, companies often end up spending more time correcting mistakes. Lack of real-time analytics When data is scattered across multiple spreadsheets, files, or systems, it becomes challenging to get a clear and accurate view.

    API Gateway Authorizers: Vulnerabilities By Design (be careful!)
    I had the benefit of joining the AWS Community Day in Zürich this week, most went as expected but, then an interesting question came up....Does caching in API Gateway create vulnerabilities for products using Authorizer Caching? When your users call your API, you have an obvious need to verify these requests should actually be allowed. I've talked extensively about this in my academy article on what the @#!? is Auth. Even if you haven't read that article, if you are well versed in the need for users to authenticate and authorize to your specific service API and endpoints, then you get the gist. So you have a need to verify the access tokens sent by users on ever request. When using AWS this means using API Gateway, and when using API Gateway that likely means you'll be using an API Gateway…  ( 6 min )
    Behind the Scenes of a Payment Gateway: How Payment Systems Integrate into E-Commerce Platforms
    When a customer checks out on an e-commerce site and clicks “Pay,” a complex series of processes kicks off in milliseconds. This post breaks down what happens behind the scenes of a payment gateway, how it integrates into digital storefronts, and what makes the entire process secure and compliant. A payment gateway acts as a bridge between the merchant’s website and the broader financial ecosystem — including issuing banks, acquiring banks, and payment networks. Its primary role is to: Capture and encrypt payment information Authenticate and authorize transactions Communicate results back to the e-commerce platform All of this occurs in real time, typically in under 2–3 seconds. 1. Checkout Begins 2. Tokenization 3. Authorization Request 4. Authentication (Optional / 3DS / OTP) 5. Response 6. Callback or Webhook For a broader look at the payment methods modern e-commerce platforms support — from cards to UPI and wallets — you can check out this deep dive on how different e-commerce payment systems work. Security is critical throughout. Here's how it's enforced: PCI DSS Compliance: Merchants using hosted solutions are often considered SAQ-A level — the lowest risk level — since card data is never stored or handled directly. SSL Encryption: All communication between browser, merchant server, and gateway is encrypted. Tokenization: Replaces sensitive data with tokens, reducing data breach risks. 3D Secure / OTP: Adds an extra layer of authentication for card transactions. HMAC-Signed Webhooks: Used to verify that callbacks are genuinely from the gateway. Plug-and-Play vs Custom Integrations Though often invisible to users, payment gateways form a vital layer in e-commerce architecture. Their ability to securely connect the merchant, customer, and financial institutions — in a matter of seconds — is what makes modern online commerce possible.  ( 4 min )
    Exploring Baby Sign Language: Communication Strategies for Preverbal Infants by Marlene Junker
    Communication with preverbal infants is a fundamental aspect of caregiving that sets the foundation for language development and emotional connection. While infants begin to understand language from birth, their ability to express themselves verbally develops gradually over time. Baby sign language offers a proactive approach to enhancing communication during this critical stage by introducing simple gestures that infants can use to convey their needs and emotions. This innovative strategy not only facilitates earlier communication but also reduces frustration for infants who may struggle to articulate their desires through speech alone. The concept of baby sign language is rooted in the belief that infants possess the cognitive ability to understand and replicate gestures before mastering…  ( 5 min )

    Best WAF for Beginners in 2025: Why SafeLine Beats Traditional WAFs
    Looking to secure your web app, but overwhelmed by complex firewall rules and confusing configurations? You’re not alone. In 2025, developers—especially beginners—need a Web Application Firewall (WAF) that’s powerful and practical. That’s where SafeLine WAF comes in. Most traditional WAFs rely on regular expressions (regex) to detect attacks. A common engine like ModSecurity powers over 80% of WAFs globally. Let’s take a look at how they work: union[\w\s]?select — matches when both “union” and “select” appear \balert\s*\( — matches common XSS patterns like alert( Sounds logical, right?

    esProc SPL & MongoDB: A Match Made in Data Heaven
    MongoDB, as a mainstream NoSQL database, has become a powerful tool for handling unstructured data thanks to its flexible document structure. However, as anyone who’s used it knows, its computing capabilities leave much to be desired. The trade-off of NoSQL is sacrificing the simplicity of SQL. Let’s take the example of finding the top 10 customers by order amount. With SQL, you can accomplish the task with a single SELECT TOP 10 statement. However, with MongoDB, you’ll need to use these three operators: $group, $sort, and $limit, and implementing cross-collection joins requires painstakingly chaining multiple $lookup stages – akin to manually assembling building blocks step by step. What’s even more frustrating is that advanced operations like window functions simply can’t be implemented …  ( 4 min )

    Stop Copy-Pasting Dependency Injection Setups , Understand It First
    I just copied the Hilt setup from a Medium post and now everything works… kinda?” Dependency Injection (DI) is not a “setup once and forget” tool. Yet that’s how many Android devs treat it — slap in Hilt, paste some boilerplate, sprinkle a few @Injects and call it architecture. Fragile codebases Silent crashes Poor testability Misunderstood scopes Let’s break down why blindly copying DI setups (especially Hilt/Dagger) is risky. You Probably Don’t Understand Scoping**** kotlin @Singleton class AnalyticsTracker @Inject constructor() { ... } Looks innocent, right? But where is @singleton scoped to? The Application component? An Activity? If you don’t explicitly bind scopes to the right lifecycle, you might hold onto context longer than you should, leaking memory or breaking navigation. Y…  ( 4 min )
    A Website Without a Strategy Behind it Is Doomed to Fail
    If your website doesn’t have a strategy behind it, it’s not going to do much for your business. Let’s be honest, if your website doesn’t have a strategy behind it, it’s not going to do much for your business. So let’s go through the these steps to build a web strategy that actually works. Think about it this way: a website is something you have to pay for. But a website with a clear, well-executed strategy behind it? That’s something that pays for itself — again and again — by bringing in new customers. But that only happens if you get it right. One of the biggest mistakes I see companies make is this. When it’s time to redo their website, they start thinking in terms of a redesign. So they go out and hire a web designer, who may or may not do any real discovery work to put a strategy in p…  ( 4 min )
    【HarmonyOS 5】如何给未知类型对象定义类型并使用递归打印所有的Key
    ​ 关键词:嵌套对象、类型、递归、未知类型 目录 使用 Record 与 ESObject 定义未知对象类型 递归打印未知类型对象的key 在鸿蒙应用开发中,所有的数据都必须定义类型,且不存在 any 类型,那么我们当遇到 key 值可能随时变化的情况时,如何获取该 object 中每一个 key 对应的数据呢? 本期以如下 object 为例,下方对象报文可能会根据使用时间或服务商的变化,"153" 字段可能会变成 "278" 等未知字符串、"5G" 字段可能会变成 "4G",那么当 key 值不断变化的同时应如何获取 "isShow" 字段的 "Y" 值? "cfg": { "153": { "5G": { "isShow": "Y" } } } 在鸿蒙中,已经不支持索引签名的类型写法(如:[key: string]: string | number),所以需要使用提供的 Record 与 ESObject 类型,在复杂类型场景使用,所以我们可以直接嵌套定义如下类型即可。 type objType = Record>>> let obj: objType = { "cfg": { "153": { "5G": { "isShow": "Y" } } } } 注:其他明确 key 与 value 类型的场景不建议使用 Record 与 ESObject 类型,养成良好开发习惯,标注好对应数据类型。 鸿蒙中不支持 for... in 形式的打印,所以对于该种复杂嵌套对象,我们可以自行编写简单的 for 循环,递归调用即可。 /** * 打印对象所有的 key * @param obj */ handleKey(obj: objType | string) { let keys = Object.keys(obj); for (let i = 0; i " + keys[i]); if (typeof obj[keys[i]] === "object") { this.handleKey(obj[keys[i]]) continue } // 打印 isShow 最终值 if (keys[i] === "isShow") { console.log("luvi > isShow最终值:" + obj[keys[i]]); break } } } // 调用 this.handleKey(obj) 输出结果: 该篇文章为开发时临时记录,开发经验如上,若对 TS 基础类型写法存在疑惑可查看 TS 官方文档,Record 与 ESObject 类型为鸿蒙的 ArkTS 类型,详细用法可前往 HarmonyOS 开发者官网了解。 ​  ( 3 min )
    🎯 How to Structure the Perfect Answer for “Tell Me About Yourself” in 2025 Interviews 🗣️
    The “Tell me about yourself” question is way more than a simple introduction, it’s your golden chance to show both your technical expertise and your human side.

    From Google Sheets to a Scalable SaaS: Building Konquista with Python and Django 🚀
    Imagine spending hours daily cleaning phone numbers and sending 1,000 WhatsApp messages by hand. That was my reality last year, juggling lead follow-ups for 20+ clinics.

    Git Reset Cheat Sheet: Soft vs Hard (With Example)
    📘 Scenario Setup You have the following Git commit history and some uncommitted changes: A commit - "A code" B commit - "B code" C commit - "C code" D commit - "D code" --> Working directory has "E code" (uncommitted changes) git reset --soft What it does: Moves the HEAD pointer back to commit B Keeps your current working directory as is C and D are removed from commit history but remain in your code All changes (C, D, E) are staged (ready to be recommitted) ✅ Good for: Squashing commits or redoing commit history 🗂️ Result: E code, D code, C code = still in files and staged Git only shows A -> B in the commit log git reset --hard What it does: Moves the HEAD pointer back to commit B Deletes all changes made after commit B from both the history and your code Everything from C, D, and E will be wiped from disk ⚠️ Warning: This is destructive and not recoverable unless you use git reflog 🗂️ Result: Only A code and B code remain All changes after B are lost 🧠 Summary Table Reset Type Do code C/D/E remain in files? Do commits after B stay in history? git reset --soft ✅ Yes ❌ No git reset (default = --mixed) ✅ Yes (unstaged) ❌ No git reset --hard ❌ No (code deleted) ❌ No Use git log to find the commit hash you want to reset to Use git reflog if you need to recover accidentally lost commits after a --hard reset 📌 Stay safe — commit often and back up before using --hard!

    Seccomp in Docker: Locking Down System Calls for a Leaner Attack Surface
    While containers offer a convenient and efficient way to package applications, they still share the host’s kernel, which introduces a set of security concerns. Every process inside a container has the potential to make system calls to the host kernel, and that opens the door to possible exploitation. Docker’s support for seccomp (short for secure computing mode) provides a vital mechanism for limiting the system calls that containers are allowed to make. This significantly reduces the potential for abuse if a container is ever compromised. Seccomp works by allowing or denying specific system calls made by processes. Linux exposes hundreds of system calls, but the vast majority of containerized applications only need a small subset to function. By filtering out unnecessary or dangerous syst…  ( 5 min )

    📡 A Practical Guide to Using WebSockets in Real-Time Apps
    In a world where users expect everything to be real-time — chat apps, dashboards, notifications, live updates — WebSockets have become a foundational tool for modern frontend developers. If you're still relying solely on REST APIs and polling to handle dynamic data, it's time to level up.

    🧠 Without a Sketch, You Get a Fish on a Tree
    In software development, words alone often fail us. “simple dashboard,” the PM imagines a KPI-heavy screen, and the developer delivers a login page. Not due to incompetence—just a lack of shared visual understanding. Imagine this: you're a tree trying to describe a bird. amphibious fish. ✅ Technically functional. This is why visual designs aren’t nice-to-have—they’re essential. You don’t need high-fidelity UI every time. Visual design includes: ✏️ Wireframes (rough structure) 🧩 Mockups (detailed visuals) 🧻 Whiteboard sketches (quick flows) 📄 Paper doodles (yes, even that) Even a crude sketch on paper can align teams better than a 10-minute explanation. Here’s what visual clarity unlocks: 🧭 Aligned intent – Everyone’s on the same page ⏱️ Faster delivery – Build once, not three times 🔍 Caught edge cases early – Before they’re in production 📢 Inclusive feedback – Even non-tech folks get it A visual is a contract of understanding. Before your next sprint, pick up a pen or open a whiteboard—even if the result looks like abstract art. Your future self (and your dev team) will thank you.  ( 3 min )

    Anime Design Pattern
    Ready to supercharge your TypeScript with six battle-tested design patterns—shōnen-style? Whether you're commanding a pirate crew or mastering ninja techniques, these patterns will make your code as legendary as your favorite anime heroes. Let's dive into production-ready examples that actually work in the real world! Every pirate crew needs exactly one captain. Our hardened Singleton ensures you can appoint the captain only once—and locks down the instance to prevent tampering. class PirateCrew { // Holds our single crew instance private static instance: PirateCrew; // Tracks who's captain (null until first assignment) private captain: string | null = null; // Private so nobody can do `new PirateCrew()` outside private constructor() { // Lock down the instance: no one ca…  ( 6 min )

    🚀 AWS EC2 Public DNS Now Supports IPv6 — Here's Why That's a Big Deal
    If you're building modern, internet-facing applications on AWS, here’s a simple but powerful update you’ll love: EC2 Public DNS names now support IPv6 (AAAA records). 🎉 Before: EC2 Public DNS names (like ec2-203-0-113-25.compute-1.amazonaws.com) only pointed to the IPv4 address (A record) of your EC2 instance. If your instance was IPv6-only, the DNS name didn’t work. You had to: Use the raw IPv6 address (ugly and hard to manage), or Set up a custom domain using Route 53. Now: EC2 Public DNS names also return AAAA records that point to your instance’s IPv6 address. This means: You can access your EC2 instance over IPv6 using the default AWS DNS name — no extra setup needed. You launch an EC2 instance with only an IPv6 address: IPv6: 2600:1f18:abcd::1234 DNS: ec2-203-0-113-25.compute-1.amazonaws.com Before: You had to use: http://[2600:1f18:abcd::1234] Now: You can just use: http://ec2-203-0-113-25.compute-1.amazonaws.com And it’ll resolve to your IPv6 address automatically! 🎯 This update: Makes IPv6 adoption easier Removes the need for custom DNS hacks Supports a smoother transition to dual-stack or IPv6-only environments Helps future-proof your cloud apps It's a small change, but it removes friction from a common use case — especially for teams prioritizing IPv6, building scalable APIs, or serving international customers. 💬 Have you started moving to IPv6? Are you running dual stack or IPv6-only workloads in AWS? Share your experience in the comments!  ( 3 min )

    How iOS Sideloading Actually Works in 2025: Dev Certs, AltStore, and the EU Exception
    Sideloading apps on iOS has always been a cat-and-mouse game. Unlike Android, where APKs can be freely installed, iOS enforces strict rules: all apps must be signed and typically installed via the App Store. But in 2025, there are still several ways—some official, some unofficial—to install unsigned or non-App Store apps on an iPhone. Let’s explore the main sideloading methods that work today, how they technically function, and the pros and cons of each. 🔹 AltStore (Apple ID Certificate Signing) AltStore uses Apple’s official development certificate infrastructure to let users self-sign apps using a free Apple ID. When you log in to AltStore, it sends a request to Apple’s developer portal to generate a temporary provisioning profile tied to your Apple ID, device UDID, and app bundle ID. E…  ( 4 min )

    SafeLine's Waiting Room: A Smarter Way to Handle HTTP Floods
    As someone who's used SafeLine WAF for over a year, I was thrilled to get early access to their latest update — version 7.2.3 — and no, this isn’t a sponsored post. I reached out myself to try it, and here's my honest take. One of the highlights in this version is the Waiting Room, a new feature built to defend against HTTP flood attacks by smoothing traffic spikes — essentially a smarter rate limiter. The concept is simple but powerful: "When too many users access the site at once, the Waiting Room kicks in to flatten the traffic peak." Sounds like a queue system? That’s exactly what it is. And it works beautifully. Unlike traditional DDoS attacks that flood bandwidth, HTTP flood attacks target the application layer (Layer 7). Attackers mimic real users, sending massive numbers of HTTP r…  ( 4 min )

    DevLog 20250522: Serverless & Serverside vs Client Side Rendering
    Full Title: Serverless vs Client-Side Rendering vs Dynamic Content (Server-Side Rendering) vs Compiled/Code Generation for Static Sites There is a lot of confusion about the term "dynamic website" for laypeople. Let's clear that up first: "dynamic" here doesn't mean sleek animation or any sort of table filtering—it refers to whether the website content itself is variable, can change based on conditions, or is fetched from some server or database. The essence of a dynamic website is that it's constructed at runtime, can change based on conditions, and is opposed to "static," meaning the contents are fixed and will not change unless someone modifies the source. In the case of the web, the source usually means the HTML itself. Also, "serverless" doesn't mean there is no server. There must be …  ( 5 min )

    Covid-19, not début de bilan ?

Anticipated to reach over 50% prevalence, by 2030, individuals with bipolar disorder (BD) will be predominantly aged 50 or above. Yet, older age bipolar disorder (OABD) has not been studied thoroughly enough. Although large-scale prospectively collected data organized by key dimensions is constrained, it potentially allows for investigating several fundamental questions regarding BD's effect on this patient subgroup. The co-occurrence of latent tuberculosis and hepatitis B virus (HBV-LTBI) in the U.S. population lacks thorough epidemiological study.

    5 Common UI/UX Mistakes in Business Apps (And How to Avoid Them)
    Ever build a business app that runs perfectly, only for users to… hate it? Been there. You’ve got clean endpoints, automated workflows, bulletproof logic—and yet support tickets keep coming in like: “Can’t find the thing I need.” “Where’s the Save button?” “This page is weird on my phone.” Turns out, bad UX can ruin even the best backend. “It Works Fine” Isn’t the Same as “It’s Usable” As devs, we’re often laser-focused on functionality. That makes sense. We want our apps to be fast, secure, and integrated properly. But if nobody can use what you built without training, duct tape, or daily rants, that’s not a win. That’s a failure in disguise. Here are 5 UX sins I’ve made (and seen) way too many times—plus how I avoid them now using Bellini, our app builder at Lonti. 1. Trying to Fit E…  ( 4 min )

    Node.js' config Library Shouldn't Be Used in TypeScript
    Coming back to typed 100% AWS Lambda API’s, I’m convinced the config module is an anti-pattern if you’re using TypeScript. Been away from typed server-side for about 4 years. While the 1st I had ReScript on the back-end in Amplify, the rest of the companies I was at did JavaScript/Python. In those languages, dynamic, sleek, easy to use global variables are nice for smaller projects with quick deploys. Like types? Nope; all the allure dynamic languages have for “use a global proces.env.NODE_ENV to grab some dev.json that is magically inherited from default.json” suddenly screams “Why is this all un-typed, un-parsed without Zod, not wrapped in a Result, and why is config not used via dependency injection? Globals… in 2025?” Then you realize… you don’t even need anything beyond some simple types + 1 helper function, and you’ve got a type safe, environment aware configuration. First define your default config, equivalent to config’s “default.json”. Second, define your dev and prod config, extending the default (both in types and in values). Finally, create a get method, passing in process so you can unit test it with a stub vs. using it as a global variable. An improvement would be to pre-parse NODE_ENV so you don’t need a default in the switch. JavaScript, I’m fine with the config module. In TypeScript, it’s dangerous and shouldn’t be used in Node.js.  ( 3 min )
    Why We Almost Gave Up on Our App—Until We Fixed the UX
    Have you ever build something for months… only to realize no one actually wants to use it? That was us. We had what we thought was a solid mobile app. The idea was validated. The features were there. But when we finally launched, the numbers just didn’t add up: High drop-off during onboarding Users signing up, but never coming back Confused feedback like “I don’t get what I’m supposed to do” At first, we thought it was a marketing issue. But turns out—it was our UX. The Pain Wasn’t the Product. It Was the Experience. If you’ve ever seen a user just stare blankly at your app screen and then close it, you know the pain. So We Got Help—From People Who Actually Do This for a Living Clear user journeys Tiny details like button placement and loading feedback Making sure users feel in control—not overwhelmed That’s when we came across a UX team in Singapore called Codigo. We weren’t even looking for an agency at first. But their UX case studies caught our eye—especially how they think through micro-interactions and user psychology. It wasn’t just design—it was experience strategy. Why I’m Recommending Them (Even Though I Don’t Usually Do This) We worked with Codigo because we needed real UX help, and they delivered. What I appreciated most: They interviewed our users before designing anything Their clickable prototypes were ready within weeks Every feedback loop felt like a collaboration, not a handoff Long story short: our bounce rate dropped, engagement rose, and people finally “got” the app. What You Can Learn (Even If You Don’t Hire Anyone) Don’t assume users think like you Fancy UI means nothing without flow clarity Test your onboarding with someone’s mom or uncle. Seriously. Final Thought They’ve worked with banks, startups, and even government apps. But most importantly, they get that UX isn’t a luxury—it’s the core of your product. 👉 If you’re curious, here’s their UX approach: https://www.codigo.co/services/user-experience No fluff.

But to my greatest surprise, when I copy-paste my final result, which I tested many times in my local editor (pyCharm), into their online editor for submission, I noticed that their online editor doesn't support windows creation (tkinter and ttkbootstrap).

    BitLocker Limbo PSA
    PSA: Do not enable BitLocker unless you immediately activate it with your windows account. Friends don't let friends have BitLocker enabled unless they activate it. So, someone comes to me with a laptop - water damage, doesn't power on, ect. It's my job to simply take out the hard drive and grab whatever data I can. Ok, no problem right? It's all fun and games until I remove the hard drive from the computer and try to access it. BitLocker. WHY. Why do you have BitLocker enabled if you didn't activate it with your windows account? Here is the hard truth: If you have BitLocker enabled without activating it and something happens - like water damage - all the IT support in the world isn't going to be able to get your data. When the hard drive is removed from the original device, BitLocker is triggered. But you will never know your key to get access to your own information unless you had previously activated your key. Your assorted data, important business information, and family photos are NOT SAFE. They will be lost. Options: Save to the cloud Do routine backups elsewhere Disable BitLocker Fully activate BitLocker Do not live in limbo, you are playing with fire, only to the disadvantage of yourself! I spent the entire day, trying to figure out how I could get the data for a loyal customer. You know how bad that sucks when you can't even do the thing you are supposed to be able to do... I tried anyways. I spent all day googling work-arounds and trying a few things. Massive waste of time. Even if they can log into their Microsoft account, they will not have their BitLocker key if it was not activated. Go forth now, and save everyone.  ( 3 min )

One of the most widely used architectural patterns is the 5-layer architecture, which separates the application into logical layers, each with a specific responsibility. Let’s dive into each layer and understand its role in the system. The Presentation Layer is the topmost layer that users interact with directly. It displays data to the user and sends user commands to the application.

    Solana 'will make everyone an investor' — Solana nCMO
    The current structure of capital markets is failing to serve a broad base of investors, according to Akshay BD, non-chief marketing officer at the Solana Foundation. During a panel at the Accelerate 2025 conference, Akshay argued that blockchain technology could help address these shortcomings, claiming that Solana could “make everyone an investor or a dreamer over time.” Akshay noted growing uncertainty among investors, citing concerns from investment managers who report heightened anxiety among clients. “You have low bond yields, you have asset price bubbles, and people don't really know how the traditional asset allocation model works anymore,” he said. The 60-40 portfolio hasn’t delivered consistent returns in a long time.” He attributed some of this tension to a widening gap between i…
    Onchain privacy is a necessity in the age of AI — Shielded CEO
    Blockchain privacy tools such as zero-knowledge (ZK) proofs will become increasingly necessary to protect online user data in the age of artificial intelligence, according to Eran Barak, CEO of Shielded Technologies, the developer behind the Midnight privacy chain. In an interview with Cointelegraph at Consensus 2025, Barak said corporate service providers and centralized servers are expected to become honeypots for AI-assisted hackers and malicious actors looking to steal valuable data, including private keys, financial metadata, medical records, and government documents. Hackers targeting centralized entities have a "massive" return on investment (ROI) and are incentivized to hack centralized targets that contain millions of valuable records, the CEO told Cointelegraph. Barak added that …

    Texas governor signals support for Bitcoin reserve bill
    Texas Governor Greg Abbott has signaled support for a bill recently passed by the state House of Representatives that would establish a strategic cryptocurrency reserve. In a May 22 X post, Abbott posted a Techstory article about Texas state lawmakers’ efforts to create a Bitcoin (BTC) reserve. The story pointed out that the decision for the passage of SB 21, the bill in question, now rests on Abbott’s shoulders, roughly three months after it was introduced.  Since taking office, Abbott referred to himself as a “crypto law proposal supporter” in 2021 and suggested that he would support policies to establish Texas as a “crypto capital” in 2024. Texas was one of a handful of state-level governments that proposed setting up a strategic crypto reserve after the 2024 federal elections.    Rela…
    Crypto Biz: From shorting the Venezuelan Bolivar to shorting the US dollar
    When Venezuela was experiencing hyperinflation, Ledn co-founder Mauricio di Bartolomeo hedged against the collapsing local currency by shorting it in favor of the more stable US dollar. Today, he’s using a similar strategy — this time borrowing against his Bitcoin (BTC) to hedge against the crumbling US dollar. Di Bartolomeo connected with me during Canada Crypto Week in Toronto, where he talked about the advantages of Bitcoin-backed loans and the rapid growth of collateralized BTC lending. In our interview, he made a compelling case for continuing to stack sats, even as Bitcoin’s price keeps rising. This week’s Crypto Biz dives into our conversation with the Ledn co-founder and covers the latest business news from the blockchain world. A lesson from hyperinflation Before Bitcoin, di Barto…
    US House members call for investigation into Trump's memecoin dinner
    Members of the US House of Representatives called for the Justice Department to investigate Donald Trump’s May 22 dinner for his top memecoin investors, citing concerns about “foreign influence over US policy decisions” and “potential corruption and emoluments clause violations.” In a May 22 letter to the Justice Department, 35 House members asked the public integrity section acting chief, Edward Sullivan, to launch an inquiry over the memecoin dinner to determine whether it violated the federal bribery statute or the foreign emoluments clause of the US Constitution.  Under the emoluments clause, a US president is barred from accepting any gift from a foreign state without the approval of Congress. Bloomberg reported that a majority of the attendees at the memecoin dinner were likely forei…
    Bitcoin price ‘breather’ expected as short-term traders realize $11.6B in profit
    Key takeaways: Short-term Bitcoin holders realized $11.6 billion in profit over the past 30 days, suggesting a potential pause or local top in the market. Technical indicators show cooling momentum as retail investor sentiment falls to a 90-day low and liquidity data points to price volatility. Bitcoin (BTC) price recently hit a new all-time high of $111,800, but the bullish momentum may slow down as onchain data from Glassnode reveals significant profit-taking by short-term holders (STHs), potentially signaling a market "breather." Glassnode analysis shows that STHs, often considered traders rather than long-term investors, have realized a staggering $11.6 billion in profits over the last 30 days. This follows a sharp rebound in Bitcoin’s price, pushing past the STH cost-basis of $93,0…

    Key points: Bitcoin slipped below $109,588, but technical charts suggest traders are buying each dip. Excessive leverage in Bitcoin futures increases the risk of a quick correction. Select altcoins have turned down from their respective overhead resistance levels, signaling that the bears remain sellers on rallies. Sellers have pulled Bitcoin (BTC) back below the breakout level of $109,588, but lower levels are likely to attract buyers.

    Crypto, NFTs are a lifeboat in the sinking fiat system: Finance Redefined
    Risk appetite across traditional and cryptocurrency markets saw a sharp rise this week, helping United States cryptocurrency funds recover the capital lost to the correction of February and March, amassing over $7.5 billion worth of weekly inflows. Bitcoin (BTC) surpassed its old all-time high on May 21, two days after President Donald Trump confirmed ongoing ceasefire negotiations between Russia and Ukraine in a May 19 X post.

    ‘In ‘93, it became clear to me AI should be decentralized’ — Ben Goertzel
    It’s been 30 years since computer scientist Ben Goertzel wrote his first line of AI code, already convinced that artificial intelligence should be decentralized. Today, as the world approaches the dawn of Artificial General Intelligence (AGI), who leads this breakthrough could have profound consequences for the future of humanity. Speaking with Cointelegraph at the Consensus conference in Toronto, Canada, Goertzel said, “We’re likely to be able to launch AGI that can think and generalize beyond its training and programming within the next one to three years.” His project, SingularityNET, is a decentralized ecosystem building a global marketplace for AI services. Along the way, it has secured partnerships with Mind Network and Filecoin Foundation, invested $53 million in a modular supercomp…

    Key takeaways: Bitcoin’s performance in the current bull market and a new cohort of buyers reflect a maturing market and widening adoption.

    Spoiler alert: The future of Web3 is not blockchain
    Opinion by: Grigore Roșu, founder and chief executive officer of Pi Squared For some, the audacity of questioning the primacy of blockchain in Web3 is borderline heretical. The idea that decentralization and progress could exist without blockchains seems absurd to those who built careers around Bitcoin, Ethereum, and their descendants. Given blockchain's well-documented scaling limits, however, there is an argument to be made that Web3 doesn't actually need blockchains to thrive. Instead, it requires payment systems and verifiable settlement systems that are super fast. Blockchains are just one way to achieve that, not the only way. While blockchain solved the double-spending problem, it introduced its own architectural burden: the rigid fixation on total ordering, dictating that every tra…
    Who attended Trump’s controversial memecoin dinner?
    The top 220 holders of US President Donald Trump’s memecoin met yesterday at the president’s golf course in Virginia for an exclusive dinner and purported meet-and-greet. Attendees spent a grand total of $148 million for an “ultra-exclusive VIP reception with the president,” which crypto industry advocates and critics alike saw as a potential opportunity to discuss crypto policy with the president.  The crowd contained a number of foreign crypto executives and influencers who otherwise would not have access to the US president, raising questions around corruption and foreign influence.  Concerns were further augmented when White House Press Secretary Karoline Leavitt declined to release a list of attendees, stating that the event was a private affair outside of Trump’s presidential duties.…
    Ethereum price chart targets $4K as transaction fees hit 3-month high
    Key takeaways: Ethereum is forming a bull flag on the daily chart, with a potential breakout to $4,000. If Ethereum’s network activity and total value locked continue to grow, ETH price may see further gains. Ether’s price printed a “bull flag” on the daily chart, a technical chart formation associated with strong upward momentum. Could a strengthening technical setup and increasing transaction fees signal the continuation of ETH’s rally toward $4,000? Ethereum transaction fees rising is bullish Marketwide recovery, fueled by Bitcoin’s rise to new all-time highs and improving macroeconomic conditions, saw Ether’s (ETH) price rise by nearly 56% to an eight-week high of $2,734 on May 23, from a low of $1,750 on May 6.  This strength in price is reflected in onchain activity, with Ethereum…
    US DOJ seizes $24M in crypto from accused Qakbot malware developer
    The US Department of Justice (DOJ) has filed a civil forfeiture complaint to seize more than $24 million in cryptocurrency from Rustam Rafailevich Gallyamov, a Russian national accused of developing the Qakbot malware. According to a May 22 announcement, the DOJ unsealed charges against the 48-year-old Moscovite with a federal indictment. Gallyamov is allegedly the malware developer behind the Qakbot botnet. “Today’s announcement of the Justice Department’s latest actions to counter the Qakbot malware scheme sends a clear message to the cybercrime community,” said Matthew Galeotti, head of the DOJ’s criminal division.

    What is DNS hijacking? How it took down Curve Finance’s website
    Understanding the Curve Finance DNS hijacking On May 12, 2025, at 20:55 UTC, hackers hijacked the “.fi” domain name system (DNS) of Curve Finance after managing to access the registrar. They began sending its users to a malicious website, attempting to drain their wallets. This was the second attack on Curve Finance’s infrastructure in a week. Users were directed to a website that was a non-functional decoy, designed only to trick users into providing wallet signatures. The hack hadn’t breached the protocol’s smart contracts and was limited to the DNS layer. The DNS is a critical component of the internet that functions like a phonebook. It allows you to use simple, memorable domain names (such as facebook.com) instead of complex numerical IP addre…
    Twice lucky? Cetus’ recovery plan on Sui mirrors a Solana blueprint
    The bounty offer to recover stolen funds from Sui-based decentralized exchange (DEX) Cetus closely resembles a successful strategy used by a Solana project three years ago. It turns out that Cetus shares the same development team as Crema Finance, a Solana-based DeFi project that suffered a $9-million hack in 2022 but recovered most of the funds by negotiating with its hacker. Now, Cetus is relying on the same strategy. Cetus is asking the hacker to return all but $6 million, or 2,324 Ether (ETH), of the stolen funds in exchange for a promise not to pursue legal action. The protocol lost $223 million to an exploit on May 22. The size of the bounty has sparked backlash from users, with many calling for a formal compensation plan instead. Several community members argue that even if funds ar…
    Washington moves on crypto: Stablecoin and blockchain bills signal regulatory momentum
    In this week’s episode of Byte-Sized Insight, on Decentralize with Cointelegraph, we break down a pivotal moment for US crypto legislation.  In a 66–32 procedural vote on May 19, the US Senate advanced the GENIUS Act, a landmark bill aimed at establishing a comprehensive regulatory framework for stablecoins. Meanwhile, across the Capitol, Representative Tom Emmer reintroduced the Blockchain Regulatory Certainty Act, backed by bipartisan support. Breaking down GENIUS The GENIUS Act — short for “Guiding and Establishing National Innovation for U.S. Stablecoins Act” — seeks to answer foundational questions around stablecoin issuance and oversight. “It defines this idea of a payment stablecoin,” explained Rashan Colbert, director of US policy at the Crypto Council for Innovation, in this week…
    Ledn ditches ETH, shifts to full custody model for Bitcoin loans
    Digital asset lender Ledn is transitioning to fully collateralized Bitcoin lending and discontinuing support for Ethereum, in moves designed to consolidate its BTC-focused business and further safeguard client assets against credit risks. In adopting a full custody structure for Bitcoin (BTC) loans, Ledn will no longer lend out client assets to generate interest, the company disclosed on May 23. Instead, Bitcoin collateral will remain under full custody by Ledn or one of its designated funding partners.  “This means assets aren’t rehypothecated, reused, or loaned out to generate yield,” Ledn co-founder and CEO Adam Reeds told Cointelegraph. Reeds said the move brings the company back to its roots and aligns more closely with Bitcoin’s founding principles. “Bitcoin was created as a direct …
    US Bitcoin ETFs near record month after $1.5B inflows in 2 days

    Genius Group resumes Bitcoin buying after US court ruling
    Singapore-based artificial intelligence firm Genius Group has added more Bitcoin to its corporate treasury after being temporarily banned from doing so. In a May 22 announcement, Genius Group explained that it has resumed accumulating Bitcoin (BTC) following a favorable ruling by the US Court of Appeals. It follows Genius Group being temporarily barred from expanding its Bitcoin treasury after a US court order had banned it from selling shares, raising funds and using investor funds to buy more BTC. Genius Group announced it increased its Bitcoin Treasury 40% with the purchase of 24.5 BTC, worth around $2.7 million. The company now holds 85.5 BTC acquired for a total of $8.5 million, at an average price of $99,700 per coin. “We are pleased to be able to begin the task of rebuilding shareho…
    CZ refutes claims in latest WSJ article on Trump-linked crypto dealings
    Binance co-founder and former CEO Changpeng “CZ” Zhao has pushed back against a report in The Wall Street Journal, calling it a “hit piece” filled with inaccuracies and negative assumptions.  In an X post, Zhao criticized the publication’s portrayal of his alleged involvement with World Liberty Financial, the decentralized finance project backed by a business entity affiliated with US President Donald Trump. Trump’s sons — Eric and Donald Jr. —are involved in the management of the company.

    DeFi near-zero onboarding costs can help 1.4B unbanked: 1inch co-founder
    Decentralized finance (DeFi) platforms have a major cost advantage over traditional banks when it comes to onboarding new users, according to Anton Bukov, co-founder of decentralized exchange (DEX) 1inch. Speaking at a panel during Dutch Blockchain Week on May 22 in Amsterdam, Bukov said traditional banks spend between $100 and $300 per user to verify documents and set up accounts. Online banks, he said, spend about $20 to $30. In contrast, DeFi requires almost nothing beyond a smartphone and internet access. “Onboarding to DeFi literally costs zero,” Bukov said. “You don’t need brick-and-mortar infrastructure or lengthy verification processes. Just connect and transact.”  Bukov said that this gives DeFi an edge over traditional financial institutions in reaching the 1.4 billion unbanked p…

    Why Tether refuses to comply with MiCA
    Is Tether MiCA compliant? The EU’s new Markets in Crypto-Assets regulation, better known as MiCA, is the first major attempt by a global economic power to create clear, region-wide rules for the crypto space, and stablecoins are a big focus. MiCA mandates best practices. If a stablecoin is going to be traded in the EU, its issuer has to follow some stringent rules: 1. You need a license To issue a stablecoin in Europe, you must become a fully authorized electronic money institution (EMI). That’s the same kind of license traditional fintechs need to offer e-wallets or prepaid cards. It’s not cheap and it’s not quick.  2. Most of your reserves have to sit in European banks This is one of the most controversial parts of MiCA. If you issue a “significa…

    Hackers using fake Ledger Live app to steal seed phrases and drain crypto
    Cybercriminals are using fake Ledger Live apps to drain macOS users’ crypto through malware that steals seed phrases, a cybersecurity firm warns.  The malware replaces the legitimate Ledger Live app on victims’ devices and then prompts the user to input their seed phrase through a phony pop-up message, a team from Moonlock said in a May 22 report. “Initially, attackers could use the clone to steal passwords, notes, and wallet details to get a glimpse of the wallet’s assets, but they had no way to extract the funds,” the Moonlock team said. “Now, within a year, they have learned to steal seed phrases and empty the wallets of their victims,” it added.  One way the scammers replace the real Ledger Live app with a clone is through the Atomic macOS Stealer, designed to steal sensitive data, whi…

    ‘No questions asked’ Bitcoin launderer gets 6 years in prison

As part of the course, Nguyen was taught how to conceal his actual business from banks, crypto exchanges and state authorities by …

Republican state Representative Bill Schuette introduced House Bill 4510 on May 21, which would amend Michigan’s Public Employee Retirement System Investment Act to allow the state treasurer, currently Rachael Eubanks, to invest in cryptocurrencies that have averaged a market cap above $250 million over the last calendar year. Bitcoin (BTC) and Ether (ETH) are the only cryptocurrencies that currently meet that threshold. The bill adds that any cryptocurrencies must be held in the form of an exchange-traded product issued by a registered investment company.

    Automation and Humanity
    Automation is often depicted as a simple story of people versus machines—a narrative filled with apprehension and fear. Indeed, the anxiety surrounding job displacement is firmly rooted in historical experiences where technological leaps have abruptly reshaped employment landscapes. Yet this picture of conflict and competition misses a profound truth: automation isn’t merely replacing work—it’s fundamentally reshaping our relationship with work. Rather than being adversaries, humans and artificial intelligence (AI) are becoming partners in an evolving dance of productivity, creativity, and innovation. To grasp automation’s complex role, consider that old jobs have always faded with time—and with change comes rebirth. Current research, including findings from the World Economic Forum, consi…  ( 5 min )

    Stop Gatekeeping and Start Leading: How Real Leaders Support Junior Devs
    Let’s get this out of the way up front: If you’re calling yourself a leader but treating your junior devs like interns with Stack Overflow accounts — you’re not leading. You’re just delegating down and hoping for the best. Junior devs aren’t liabilities. They’re high-potential humans still figuring out how this industry works while we dump half-documented codebases and broken CI pipelines on them like it’s a rite of passage. Time to do better. Here’s how real tech leaders actually support their junior devs: Don’t just toss a JIRA ticket and bounce. Give them the why, not just the what. “This feature helps us reduce user churn by tightening onboarding” is miles better than “Add this button to the modal because the PM said so.” Juniors thrive when they understand the system they’re working…  ( 4 min )

    Types of Machine Learning Algorithms
    Machine learning (ML) algorithms analyze data to uncover patterns and generate insights. Based on their training approach and objectives, they can be categorized into four main types: Supervised learning uses labeled data (input features + corresponding output labels) to train models. The algorithm learns to map inputs to outputs, making predictions on new, unseen data. It’s divided into three key tasks: Classification: Predicts discrete categories (e.g., spam detection). Regression: Predicts continuous values (e.g., house prices). Forecasting: Predicts future trends (e.g., weather forecasts). Example: Predicting stock prices or customer churn. Unsupervised learning works with unlabeled data, identifying hidden structures or patterns. Since there’s no "correct answer" provided during training, the algorithm explores similarities/differences autonomously. Common techniques include: Clustering: Groups similar data points (e.g., customer segmentation). Dimensionality Reduction: Simplifies data while preserving key features (e.g., PCA for visualization). Example: Market basket analysis or anomaly detection. A hybrid approach combining small amounts of labeled data with large unlabeled datasets. This is cost-effective when labeling data is expensive or time-consuming. Applications: Speech recognition, medical image analysis. RL trains an agent to make decisions via trial and error, using feedback from rewards/penalties. The agent learns optimal strategies by interacting with an environment. Use Cases: Game AI (e.g., AlphaGo), robotics, autonomous vehicles.  ( 3 min )
    Why Your MongoDB Transactions Aren’t Working in Docker — and How to Fix It 🚨
    You’ve added startSession() and startTransaction() to your Mongoose code, only to be greeted with: Transaction numbers are only allowed on a replica set member or mongos If you’re running MongoDB in a standalone Docker container, transactions simply won’t fire — because MongoDB requires a replica set (even if it’s just one node) to support transactions. Let’s break this down from the ground up — no prior MongoDB knowledge assumed. A replica set is a group of MongoDB processes that maintain the same data set. One member is the primary, which receives all write operations. The others are secondaries that replicate (copy) data from the primary in real time. Primary: accepts reads (depending on your read preference) and all writes. Secondary: copies data from primary; can optionally serve re…  ( 6 min )

    How PostgreSQL logical decoding and plugins work
    When you're building a change data capture (CDC) pipeline with PostgreSQL, one of the first decisions you'll make is which output plugin to use. These plugins determine how your database changes get formatted and delivered—whether you're replicating to another Postgres instance, streaming to Kafka, or delivering changes to a webhook. But what exactly are these plugins, and how do they differ in practice? Let's dive in with a concrete example and explore your options. To understand how different output plugins work, let's start with a simple scenario. We'll set up logical replication, make a change, and see how different plugins format that change.

    Error MikroTik DNS over HTTPS After Upgrading to 7.19
    Hey fellow network admins! 👋 So I've got this habit of keeping my MikroTik router updated to the latest firmware version. Usually, it's smooth sailing - upgrade, reboot, everything works perfectly. But recently, I hit a weird snag that had me scratching my head for a while. I just upgraded my MikroTik from version 7.18.2 to 7.19, expecting the usual seamless experience. Instead, my users suddenly couldn't browse the internet. Not exactly what you want to hear on a Monday morning! 😅 Time to fire up WinBox and see what's going on. After connecting to my router, I started digging through the logs and found this lovely error message repeating over and over: DoH server connection error: SSL: ssl: no trusted CA certificate found (6) Well, that's not good.

    Linux in Action: Mastering ACLs (Access Control Lists) for RHCSA
    Introduction Basic Unix permissions (rwx) work well for many scenarios—but they can fall short when we need fine‑grained access control. Access Control Lists (ACLs) extend the traditional model, allowing you to grant specific permissions to additional users or groups without altering the file’s primary ownership. ACL management is a core skill assessed in the Red Hat Certified System Administrator (RHCSA) exam and is vital for real‑world multi‑tenant environments. 📌 This guide focuses on the exact depth of ACL knowledge required for RHCSA, with practical demonstrations you can reproduce in a lab.

    How I Manage Localhost Port Conflicts With an AI Agent
    Localhost Ports Hoarding I'm perpetually drowning in open tabs. Yes, I do need Bluesky, ChatGPT, Claude, Goose, Cursor, Discord, Slack, Netflix, and Google Docs all open at the same time. I've learned that tab management isn't my only vice. "Hi, my name is Rizel, and I'm a localhost ports hoarder. 👋🏿" It always starts innocently with me running one project that uses localhost:3000. Then a teammate pings me to review their PR. Their project also runs on localhost:3000. Fortunately, modern frameworks are smart enough to automatically bump to ports 3001 or 3002. Before I know it, 3003, 3004, and 3005 are running too, and my laptop sounds like it’s about to take off as it crawls under the weight of too many processes. Typically, freeing up ports involves running the following commands: # S…  ( 4 min )

    What Is a Multisig Wallet?
    The world of cryptocurrency is still very much like the Wild West, not just in terms of price volatility but also regarding security. Holding digital assets is still very risky, from forgetting your private keys to hacks that steal billions of dollars. This is why the question “What is a multisig wallet?” is one that is very relevant and important, and often searched for online. Consider that in 2022 alone, hackers managed to steal over $3.8 billion in crypto. Most of this was done by defeating wallet or protocol security measures. This is where multisig wallets or multisignature wallets come in. These wallets are like shared vaults and offer better security by requiring multiple approvals for every transaction. In this article, I’ll take a look at what a multisig wallet is, how they wor…  ( 9 min )

    The Challenge of Error Handling in Modern Applications, a pragmatical approach.
    The days when adding dynamism to a web page was limited to a few lines of jQuery are long gone. Modern web applications are complex ecosystems, interconnected with APIs, databases, and external services. This inherent complexity brings with it a constant and often underestimated challenge: error handling. In my years of experience, I’ve seen how poor error handling can crush the user experience (UX), hinder the traceability of problems, and not less important, affect the developer experience (DX). What happens when your application can't get data from the server? The possibilities are endless: an internal server error (5xx)? An authorization problem (4xx)? Perhaps your application expected a nested object like foo.bar, but bar never arrived in the response? Or a user encountered an unexpec…  ( 16 min )
    The Rise of Hybrid Frameworks
    Just a decade ago, web development was straightforward: all rendering was done server-side, meaning each click on a hyperlink loaded a new page with fully-rendered HTML. This thin client setup allowed browsers to seamlessly handle navigation and made the system ideally suited for search engine indexing. As the internet evolved, so did user expectations. Websites were no longer just static pages of information, but needed to be interactive with features such as real-time updates and dynamic content. This demand led to the creation of Single Page Applications (SPA), where the backend transformed into an API serving data, and the frontend handled rendering and interactions. In mid-2000s Gmail revolutionized web development by becoming the first true SPA project. Its seamless user experience i…  ( 6 min )

    Git Rebase -i: Clean Up Commits Like a Pro (Day 1/30)
    🔍 Introduction: Why You Need This Ever looked at your Git history and seen a mess of “WIP”, “fix typo”, and “oops” commits? You’re not alone. Most developers use git merge and live with cluttered histories. But top engineers at FAANG companies rely on git rebase -i (interactive rebase) to keep their commit logs clean, logical, and professional. In this guide, you’ll get: Interactive rebase lets you rewrite, reorder, or combine commits before sharing them. Here’s how to use it: git rebase -i HEAD~3 # Edit the last 3 commits Problem: You have 5 messy commits: # Commit list - Add login button (WIP) - Fix typo - Refactor auth logic - Fix lint error - Update README git rebase -i HEAD~5 An editor window will open showing the following. Squash “Fix typo” and “Fix lint error” into “Refactor auth logic.” Reword “Add login button (WIP)” to “Implement login button.” Drop unnecessary commits. For the next window, enter the reworded commit “Implement login button” and hit save. Result: A clean, logical history. # Commit list - Refactor auth logic - Implement login button - Update README --autosquash Manually marking commits for fixup is tedious. Instead, use --autosquash to automate it: 1. Mark commits as fixes: git commit --fixup=COMMIT_HASH 2. Run rebase with --autosquash: git rebase --autosquash HEAD~N # Accidentally left a small change from committing? Fix it: git add . git commit --fixup=abcd123 # commitSHA of the original commit git rebase --autosquash abcd123 # No manual editing! Why FAANG engineers love this: Saves hours of manual rebasing. Keeps history clean without effort. ⚠️ Golden Rule: Never rebase pushed commits (unless you’re alone on the branch). Already pushed an incorrect rebase to repo. No worries, use this. git reflog # Find the commitSHA for pre-state git reset --hard commitSHA [alias] ri = rebase -i ras = rebase -i --autosquash Up Next in the Series: Day 2: git cherry-pick—The Surgical Way to Move Commits.  ( 4 min )

    From React to Swift: Why I’m Exploring iOS Development
    I’m a frontend developer who has worked with Angular and React for the past few years. Both frameworks have taught me a lot, but React in particular has dominated my recent experience. It’s popular, flexible, and powerful — no doubt about that. But despite its upsides, working with React in real-world production apps slowly pushed me to a breaking point. React often felt… messy. Even though React gives you freedom, that same freedom can become a burden, especially as your project grows. Every team ends up inventing their own structure, folder naming conventions, and state management preferences, and you’re left stitching everything together with dozens of third-party libraries. It’s like building a city with Lego bricks… from a thousand different boxes. The biggest pain points for me were:…  ( 5 min )

    Understanding the Cost of Abstractions in .NET
    Clean code isn't always fast code. While abstractions like LINQ, interfaces, or dependency injection make our code cleaner and more maintainable, they can introduce runtime overhead. And in performance-critical paths, those costs add up quickly. In this article, we'll walk through how common .NET abstractions can degrade performance, explore when to use them with care, and share techniques to avoid unnecessary overhead. LINQ is incredibly expressive, but it's not always the most efficient — especially in tight loops or "hot paths." var filtered = data.Where(x => x.IsActive).ToList(); ` While flexible, LINQ's deferred execution model can lead to hidden costs. The .ToList() call here forces immediate materialisation, introducing new allocations for the list and potentially temporary iterat…  ( 5 min )
    How We Built a Scalable B2B Fashion Platform for Ethnic Bottomwear Using Shopaccino
    Why We Chose Shopaccino as Our eCommerce Engine We evaluated several platforms (Shopify Plus, WooCommerce with B2B plugins, and Magento), but chose Shopaccino for three primary reasons: Built-in B2B features like bulk pricing, GST management, and dealer-specific login. Flexible category-level control and filtering that suited our product structure. Localized support with experience in Indian commerce logistics.

    Meet MCP: The Simple Rulebook Behind Smarter AI Prompts
    When you use a smart AI assistant or agent—whether it’s helping write code, answer questions, or run a workflow—there’s a lot going on behind the scenes. One key challenge is how to talk to the language model clearly and consistently. That’s where Model Context Protocol (MCP) comes in. Model Context Protocol (MCP) is a simple but powerful idea: it’s a standard way for an AI agent to organize and format the prompt it sends to a language model. You can think of it like a checklist or recipe. Instead of throwing together bits of context in random ways, MCP tells the agent what information to include, in what order, and how to label it. Language models are smart, but they’re also sensitive to how you talk to them. If your prompt is messy, missing key details, or mixes things up, the model migh…  ( 4 min )

    Understanding Idempotency in APIs and Distributed Systems
    Introduction In modern software development, APIs and distributed systems must handle failures gracefully. Network issues, timeouts, and client retries can lead to duplicate requests, causing unintended side effects like double charges, duplicate orders, or inconsistent data. Idempotency solves this problem by ensuring that performing the same operation multiple times has the same effect as executing it once. This article explores idempotency, its importance, real-world examples, and best practices for implementation. What is Idempotency? An operation is idempotent if repeating it does not change the result beyond the initial execution. Key Characteristics Same Request → Same Effect: Multiple identical requests produce the same outcome as a single request. Safe Retries: Cli…  ( 4 min )
    Tinkering Today: PyAudio
    I've been working on a karaoke game idea in Python for a bit now and I stumbled upon a small problem: The scoring system. As of now, I am able to generate an isolated vocal track and also generate the pitches for this track. So the next step, naturally, would be to figure out how to get the pitches from a live audio input stream. But given the live audio stream, I would have to be able to compare these pitches live and return that result to the user in some sort of scoring system. Furthermore, the library that is used for determining the pitches in the audio takes a bit of time (using CREPE). It is fine for processing to take a long time when generating a reference track but in practice, there needs to be a faster way. Well, for now I will tinker with PyAudio for a bit and see what I can do.  ( 3 min )

    Enabling CORS in Flask
    When you’re building a full-stack app with a separate frontend and a Flask backend, the browser’s Same-Origin Policy will block your API calls unless you explicitly allow them. Cross-Origin Resource Sharing (CORS) is the protocol that lets you opt-in. In this guide we will cover two common ways to get it done in Flask. Flask lets you set response headers directly, so you can choose which endpoints get which CORS rules. If your frontend lives at https://myapp.com, you can allow it like this: from flask import Flask, request, jsonify, make_response app = Flask(__name__) @app.route("/api/hello") def hello(): resp = make_response(jsonify({"msg": "hi"})) # allow just one origin resp.headers["Access-Control-Allow-Origin"] = "https://myapp.com" return resp Whenever the browser …  ( 4 min )
    How to pass a TypeScript function as a parameter
    Written by Kealan Parr✏️ This article explores how to pass functions and structured objects as parameters in TypeScript. It highlights use cases, syntax differences, and practical scenarios where each may be preferred, especially when working with function types, inheritance, excess property checks, and optional fields. In JavaScript, functions are considered first-class citizens, which means they can be handled like any other type of variable, including numbers, strings, and arrays. This allows functions to be passed into other functions, returned from functions, and assigned to variables for later use. This feature is heavily used in asynchronous code, where functions are often passed into asynchronous functions, often referred to as callbacks. But this can be tricky to use with TypeS…  ( 14 min )
    Qubit-Efficient Encoding Techniques for Solving QUBO Problems
    🧠 Introduction Classical algorithms are already incredibly effective at solving many optimization problems, especially when the number of variables is in the low thousands. However, when scaling up to problems involving tens or hundreds of thousands of binary variables, classical solvers begin to falter due to the combinatorial explosion in the search space. Quantum computing offers a compelling alternative, not by brute force, but by exploring exponentially large solution spaces in parallel using quantum superposition and entanglement. One popular quantum algorithm for such problems is the Quantum Approximate Optimization Algorithm (QAOA) [3], a textbook example of a variational quantum algorithm (VQA). However, QAOA requires one qubit per binary variable, which becomes prohibitively r…  ( 8 min )

    Automated Deployment for Small Teams: How to Start with one click?
    If you’ve ever delayed pushing to production because “it’s just too much right now,” you’re not alone. For small teams - especially startups and indie developers, deployment often becomes the most dreaded part of the workflow. Not because it’s hard, but because it’s messy, time-consuming, and filled with “extra stuff” like YAML files, CI/CD config, and infrastructure setup that feels disconnected from actual product building. So what if there was a simpler way? What if deploying your app was as easy as pushing code - and that was it? When you’re a 3-person team juggling product, support, design, and roadmap decisions, no one wants to spend hours setting up Kubernetes manifests or debugging a Jenkins pipeline.

    Focus Containment: The Broken State of Keyboard Navigation
    As web developers, we strive to create experiences that work for everyone. The central problem? Focus containment. Before diving into the technical aspects, let's take a look why this matters: Accessibility: Many users with motor disabilities rely entirely on keyboards Power users: Keyboard shortcuts enable efficient navigation for all users Screen reader users: Rely on consistent focus management to understand page context A broken focus experience isn't just an inconvenience - it can render a website completely unusable for a significant portion of your audience. To be fair, defining a common expaction for keyboard navigation is tricky. But many users expect web content to behave as predictably as the browser UI itself. Think about it when you hit Tab while in the URL bar, you know exac…  ( 8 min )
    🚀 Understanding OFFSET in PostgreSQL
    📌 What is OFFSET? The OFFSET clause in PostgreSQL is used to skip a specific number of rows before starting to return rows from a query. It’s often used along with the LIMIT clause to implement pagination — a technique to fetch a small chunk of data at a time. 🔧 Syntax SELECT column1, column2 FROM table_name OFFSET number_of_rows_to_skip; Usually, it's paired with LIMIT like this: SELECT column1, column2 FROM table_name LIMIT page_size OFFSET number_of_rows_to_skip; 📊 Real-World Example Let’s say you have a table called students: id name grade 1 Alice A 2 Bob B 3 Charlie C 4 Diana B 5 Edward A Example 1: Simple OFFSET SELECT * FROM students OFFSET 2; Output: id name grade 3 Charlie C 4 Diana B 5 Edward A This query skips the first 2 rows and returns the rest. Example 2: LIMIT with OFFSET (Pagination) Let’s say you want to show 2 students per page: -- Page 1 -- Page 2 -- Page 3 This way, you only load a few rows at a time, which is better for performance and user experience. 🛠 When to Use OFFSET To implement pagination in web applications. To load large datasets incrementally. To skip over records during testing or debugging. ⚠️ Caveats Performance: Using large OFFSET values can slow down performance because PostgreSQL still scans through skipped rows internally. Duplicate or Missing Records: If the data changes between paginated queries (like inserts or deletes), you might get duplicates or miss some records. ✅ Pro Tip: For large datasets, consider using keyset pagination (e.g., with WHERE id > last_seen_id) for better performance. 📚 Summary OFFSET Skips N rows before fetching LIMIT Restricts number of rows returned Together, they form the backbone of pagination in SQL queries.  ( 3 min )

    Cache Busting in Ionic 3
    Browsers will often cache static assets to improve performance. This can cause issues when a new version of the application is deployed but the browser is still reading the old cached version. With cache busting, we append a hash to the static file names e.g vendor.js becomes vendor.437b51dcc2.js. When a deployment is made the hash changes e.g vendor.437b51dcc2.js may change to vendor.74t74t5tt.js. With cache validation enforced by the meta tags below, the browser will first check if the there is a new version of the file before using the cached versions. It will thus request for the new version of the file. (Add these to your src/index.html as Step 1) Step 2 var …  ( 5 min )
    Linked Lists — A Core Building Block in Data Structures
    Arrays usually get all the love. They're easy to use, built into every language, and great for most tasks. But there’s another data structure that quietly powers a lot of efficient solutions: the linked list. It’s not about speed for direct access — it’s about flexibility, efficient insertions, and being the foundation for structures like stacks, queues, and even graphs. Let’s give it the spotlight it deserves. A linked list is a linear data structure made up of nodes. A value A reference (or pointer) to the next node A simple representation: [10] → [20] → [30] → null Unlike arrays, elements in a linked list are not stored in contiguous memory. This makes linked lists: More memory flexible Ideal for fast insertions and deletions Slower for direct access to elements by index Use a linked…  ( 5 min )

    API Gateway vs Service Mesh
    Introduction As organizations adopt microservices architectures to improve scalability, agility, and team autonomy, managing service communication becomes a central concern. Two popular infrastructure components that help tackle these challenges are API Gateways and Service Meshes. While both deal with communication and traffic management in distributed systems, they serve distinct roles and operate at different layers of the application stack. In this article, we’ll explore the key differences between API Gateways and Service Meshes, their purposes, features, and when you might use one—or both—in your architecture.

    Sharing Variables Across TypeScript and Bash Scripts
    Problem While working on a project, I came across an interesting issue. Multiple TypeScript and bash scripts needed to read from or write to a shared file. Thus, the scripts needed the file path (directly or indirectly). The question is: if the file location changes, how should I structure the code such that only one file needs to be updated (and thus reduce the risk of missing updates in various scripts)? The Typescript scripts could import the file path in a utils.ts and use a getSharedFilePath function e.g. import { getSharedFilePath } from "utils"; const SHARED_PATH = getSharedFilePath(); BUT! What about the bash scripts? They still hardcoded the path e.g. SHARED_PATH="path/to/shared/file.json"; Pros: ✅ DRY for Typescript files (but not for bash scripts) Cons: ❌ Violates DRY princi…  ( 4 min )

    Write Smarter SQL: 5 Tips to Level Up Your Queries
    SQL (Structured Query Language) is the foundation of interacting with relational databases. Whether you’re building a side project or working in a production environment, writing efficient and readable SQL can save you hours of debugging and optimization. In this post, I’ll share 5 practical tips to help you write smarter SQL—whether you’re using PostgreSQL, MySQL, or SQLite. 1. Be Specific with SELECT Bad: SELECT * FROM users; Better: SELECT id, name, email FROM users; 2.Use Table Aliases for Clarity Bad: SELECT * FROM orders o JOIN customers c ON o.customer_id = c.id; Cleaner: SELECT o.id AS order_id, c.name AS customer_name Good aliases make your queries easier to scan, especially in team environments or long queries. 3. Index Strategically Example: CREATE INDEX idx_users_email ON users(email); SELECT * FROM users WHERE email = 'user@example.com'; 4. Keep It DRY with Common Table Expressions (CTEs) Instead of nesting subqueries: SELECT name FROM ( Use a CTE: WITH user_counts AS ( 5. Use CASE for Conditional Logic SELECT name, This makes your logic explicit without post-processing in application code. N/B: SQL is simple on the surface, but powerful underneath. The more intentional you are with your queries, the better performance and maintainability you’ll get.  ( 4 min )
    Why You Shouldn’t Rely on AI in 2025 (And How Developer Communities Will Make You Better)
    Photo created using Grok It’s tempting to let AI generate your code, debug your errors, and even design your projects. But over-reliance on AI in 2025 could hurt your growth as a developer. Here’s why you should code first, ask AI second—and lean on developer communities to truly level up. 🚨 Top 10 Reasons to Not Depend on AI in 2025 1️⃣ AI Doesn’t Teach You Problem-Solving AI gives answers, not understanding. You won’t learn why a solution works—just that it does. Real skill comes from struggling, debugging, and figuring it out. 2️⃣ AI Code is Often Messy & Unoptimized AI generates working but inefficient code. Without reviewing it, you’ll inherit hidden bugs and tech debt. 3️⃣ AI Can’t Replace Human Feedback Developer communities…  ( 4 min )
    MCP Servers for Agentic Dev Platforms
    For the past couple of months, the concept of MCP has been booming. MCP (Model Context Protocol) was developed and released by the end of 2024 by Anthropic. It allows AI agents and LLMs to interact with third-party APIs in order to work with real data and allows them to make actions on your behalf. In the case of a Redis MCP, as you will see further in the blog, it means that you can search through your database using natural language. Now, to utilize MCP and allow it to interact with other APIs, you will need an MCP server that exposes tools for your agents to use. The big question is how to run your MCP servers without making life harder for your developers. Having everyone set up their own local server is tedious and invites all kinds of inconsistencies. Centralizing it as a shared serv…  ( 7 min )
    🎯 The Hidden Power of Software Testing in Modern Development
    Let’s uncover the layers of testing that silently fuel the world’s most reliable applications: Testing isn’t just about discovering defects — it's about ensuring confidence. It verifies business logic, validates user experience, and safeguards against regressions. Good testing builds trust — for both the team and the end-users. Waiting until development ends to test is outdated. Modern QA begins during planning, collaborating with developers and analysts to write better stories, define edge cases, and prepare smarter test data. Automation helps with speed, but it’s not a magic wand. Understanding what to automate (and what not to) is key. A balanced strategy combining manual, exploratory, and automated testing leads to optimal results. Today’s testers are not just script runners. They’re quality advocates, embedded in agile teams, contributing to design reviews, writing testable requirements, and driving continuous improvement. Stop counting just test cases and defect counts. Modern teams track defect leakage, test coverage gaps, and test debt — metrics that help assess not just quantity, but the impact and effectiveness of testing. Software testing isn’t a bottleneck — it’s a business enabler. The faster we test well, the faster we ship with confidence. 🚀  ( 3 min )

    Bitcoin Pizza Day 2025: 15 Years Ago, 10,000 BTC Bought Two Pizzas
    In May 2010, a man in Florida offered 10,000 Bitcoin for two pizzas. At the time, that was roughly $41 worth of BTC. In 2025, it’s worth over $1.1 billion. Sounds absurd, right? Yet it’s no urban myth. It’s a legendary milestone known as Bitcoin Pizza Day, celebrated every May 22nd as the moment Bitcoin made its first leap from code to commerce. What started with two Papa John's pizzas has grown into a global phenomenon, a benchmark in the timeline of decentralized money. This moment in crypto history now lives alongside events like Mt.

    The Anthropomorphic Paradox: Unpacking User Frustration and Misperception with Apple's Siri
    I. Executive Summary Apple's Siri, a pioneering voice assistant, has faced persistent user complaints and criticisms over the past decade, primarily stemming from its functional limitations. These shortcomings, including frequent misinterpretation of commands, shallow responses, and a notable failure to maintain conversational context, have led to widespread user frustration. This report posits that Siri's anthropomorphic design cues—its human-like voice, tone, and conversational interface—are not merely aesthetic choices but are, in fact, the fundamental cause of user misperceptions. By implicitly encouraging users to treat Siri as if it possesses genuine understanding or thought, these design elements create unrealistic expectations. When Siri inevitably fails to meet these human-level…  ( 25 min )

    Building lasting habits isn’t about sudden, massive changes — it’s about small, consistent actions repeated every day. Here are some key points from 𝗔𝘁𝗼𝗺𝗶𝗰 𝗛𝗮𝗯𝗶𝘁𝘀 by James Clear, along with simple examples to help you apply them: 𝟭. 𝗧𝗿𝗮𝗰𝗸 𝗬𝗼𝘂𝗿 𝗛𝗮𝗯𝗶𝘁𝘀: Keep a simple log or calendar. For example, mark an “X” every day you meditate. Visual progress motivates you to keep going. 𝟮. 𝗡𝗲𝘃𝗲𝗿 𝗠𝗶𝘀𝘀 𝗧𝘄𝗶𝗰𝗲: Missing a day is okay, but don’t let it turn into two days. If you skip your workout once, commit to doing it the very next day. 𝟯. 𝗦𝘁𝗮𝗿𝘁 𝗦𝗺𝗮𝗹𝗹: Begin with tiny actions, like reading one page or doing 2 minutes of exercise. This makes habits easy to start and maintain. 𝟰. 𝗨𝘀𝗲 𝗩𝗶𝘀𝘂𝗮𝗹 𝗖𝘂𝗲𝘀: Place reminders in your environment. Lay out your workout clothes the night before to cue morning exercise. 𝟱. 𝗥𝗲𝘄𝗮𝗿𝗱 𝗬𝗼𝘂𝗿𝘀𝗲𝗹𝗳: Finish your habit with a small reward — like enjoying a cup of coffee after completing a task — to reinforce the behaviour. 𝟲. 𝗕𝘂𝗶𝗹𝗱 𝗜𝗱𝗲𝗻𝘁𝗶𝘁𝘆, 𝗡𝗼𝘁 𝗝𝘂𝘀𝘁 𝗢𝘂𝘁𝗰𝗼𝗺𝗲𝘀: Focus on becoming “the type of person who writes daily,” rather than just finishing a book. Small changes add up to big results over time — consistency beats intensity! 𝗪𝗵𝗮𝘁 𝘀𝗺𝗮𝗹𝗹 𝗵𝗮𝗯𝗶𝘁 𝗵𝗮𝘃𝗲 𝘆𝗼𝘂 𝗯𝘂𝗶𝗹𝘁 𝘁𝗵𝗮𝘁 𝗵𝗮𝘀 𝗺𝗮𝗱𝗲 𝗮 𝗯𝗶𝗴 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝗰𝗲 𝗶𝗻 𝘆𝗼𝘂𝗿 𝗹𝗶𝗳𝗲?

    How to login to your remote server like Digital Ocean using SSH key on window
    SSH stands for Secure Shell. It is a cryptographic network protocol used to securely assess and manage remote computers over the Internet. You are expected to see the usage instructions like this PS C:\Users\USER> ssh If you did not see this, then you will have to install OpenSSH, which can be found in the settings of your Windows OS. Your identification has been saved in ozoSSh This signifies that the keys have been created. the file name with .pub”, • Now that you have created your droplet/server on Digital Ocean, the next thing is to copy the IP address and return to the PowerShell. • In PowerShell, you can then type; the file directory of the private key, i.e the file without the .pub suffix root@IP address of the remote server” This will prompt you to type in your passphrase used to set up the SSH key before you are logged in. The logic here is that as the SSH key pair is created, the public key is saved in your remote server; you need the corresponding private key, which the server will compare with that of the public key in order to grant you access to the remote server. If for any reason, the private key does not match the public key, you will be denied access to the server.  ( 5 min )

    How vim Prevents Blowing Up Your SSDs?
    The other day, I was going through a list of useful UNIX commands and came across tail -f. The tail command, by default, shows the last 10 lines of a file, but you can use the -n option to see a specific number of lines. The tail -f command, however, lets you watch a file for live changes. I decided to try it out by watching a file named hello.txt in the terminal while editing it using Vim. But to my surprise, no changes appeared in the output of tail -f. This made me curious, and I started digging into what was happening. That research led me to some really interesting concepts — and made me appreciate how smart Vim’s design actually is. tail -f Really Doing? To begin with, let’s understand what tail -f does.

    Google Chrome Not Working on Windows 10 or 11? Here's What Finally Worked for Me
    The Chrome browser on my Windows 10 has not been working properly for the past few months. Whenever I tried, it wouldn't open, or it would launch and freeze instantly. I tried a couple of ways to fix it, like removing the cache, reinstalling, etc. I kept pushing off, but in the meantime, I used Brave Browser, which is good. But finally, I have solved the problem. Here's how I fixed it - and how you might be able to as well. Whenever I launched Chrome: It takes time to open, or sometimes it doesn't open It froze immediately, or It would run, but the pages wouldn't load I lived with this issue for months, then switched to Brave, but I always tried to fix it because Chrome is my go-to browser all the time. Before I found the fix, I tried: Reinstalling Chrome Removed all the extensions Cleared cached and profile data Restarting the laptop Go to your Chrome settings Now, in the settings, select the System option, and you'll see options like these or maybe other options as well. I disabled the "Use graphics acceleration when available" option, and it worked fine afterwards without any freezes occurring. After disabling it, restart Chrome. I'm not sure of the exact details, but ChatGPT explained it to me in a clear and organised manner., I wish I had tried this sooner, but you know what? I got my Chrome working normally again, and I am very happy. Did this fix work for you? Got a different solution that helped?

    How To Revolutionize Clinical Trials with the Power of Voice and AI
    Introduction Traditional clinical trials are fraught with inefficiencies. The manual transcription of participant interviews, the laborious process of clinicians documenting observations, and the time-consuming effort of ensuring protocol compliance contribute to significant delays and inflated costs. These manual processes are not only resource-intensive but also prone to human error, potentially impacting data accuracy and the integrity of trial results. Voice data, in the form of spoken interviews and dictated notes, represents a vast, untapped reservoir of rich, qualitative information. However, extracting actionable insights from this unstructured data has historically been a significant hurdle.

    🧠 Who Programmed a Programming Language to Program a Program to Program Programs?
    Finally, Let Me Clear This Up Once and for All What we call programming is really just manipulating computer memory Now, a programming language is a tool humans designed But in other languages I can just say: Assembly language was created so that we don’t forget the name of a variable in memory addr... Instead of memorising the addr we can store it as short addr... Other languages I believe later tried to simplify the process... But here’s the twist Computers only understand 1 and 0 while humans understand sentences better than numbers. (E.g. if I ask you to memorise 1011011... it becomes hard. Goal is to write sentences (syntax) that we can remember. Also, programming languages themselves need to be understood by the computer. And guess what? Those compilers and interpreters are themselves programs—written in other programming languages (e.g. C++ or C)! That is... This creates a fascinating cycle Programs to write programs that write programs. Each layer builds upon the previous, hiding the complexity just so that humans can create increasingly powerful software without dealing with the tiniest detail of the hardware. So, when you ask... The answer is: Humans did. At the end of the day... It speeds up our development of a project.  ( 4 min )

    Unpoly outclasses Hotwire

    Getting a single value from a device's state in Home Assistant
    I recently acquired Netatmo smart radiator valves to manage my rooms' temperature remotely. I'm not skilled at manual tasks, but I could easily replace the old thermo-static valves. I then registered the smart ones in the Netatmo app. Finally, I integrated them in my Home Assistant via the dedicated Netatmo integration. Everything was very straightforward. I noticed that each valve not only allows remote control but also offers a state with several attributes. I wanted to extract the room's temperature indicator from it. It was not as easy as I thought it was, so I want to describe how I managed to achieve it. By default, the Netatmo valve displays a multi-valued state.

    How Predictive Analytics Is Transforming Modern Manufacturing
    Manufacturing has always been a complex balancing act—managing cost, quality, efficiency, and supply chains. Today, predictive analytics is helping manufacturers achieve that balance more effectively by unlocking insights hidden in their data. Whether it’s preventing machinery breakdowns or improving production schedules, predictive analytics is making manufacturing smarter and more efficient. In short, it’s the use of data models to forecast events before they happen. It goes beyond traditional reporting and dashboards by leveraging AI/ML algorithms to suggest proactive actions. Examples include: Predicting machine failures before they occur Forecasting customer demand Identifying quality issues early in the line Anticipating supply chain disruptions Predictive Maintenance: Algorithms detect patterns that typically precede defects—helping teams intervene before waste occurs. By predicting demand accurately, manufacturers can keep optimal inventory levels and reduce carrying costs. Some manufacturers use analytics to monitor energy usage and forecast high-consumption periods, enabling cost-saving actions. Data Collection: IoT sensors, machine logs, ERP data Data Processing: ETL pipelines, cloud-based data lakes Modeling: Python, R, TensorFlow, Azure ML Deployment: Real-time dashboards, API endpoints, embedded analytics You don’t need to boil the ocean—start with a single problem area like downtime or product defects and iterate. With tight margins and high customer expectations, manufacturers can't afford reactive strategies. Predictive analytics provides a strategic edge by reducing waste, improving efficiency, and driving innovation. 👉 Read the full article here.  ( 3 min )

    From Prompt Chaos to Presets
    InkLytic was created as an AI Content Lab to solve a specific problem: the endless loop of prompt tweaking in modern LLM-driven content creation. Prompt engineering works — until it has to scale. A single prompt might produce decent output for a blog post, but when the format changes, or the tone needs adjustment, or the audience shifts, the process starts over: rephrase, test, tweak. Here’s a typical example from early experimentation: Write a short and engaging social media post about Lionel Messi’s recent goal in the MLS. Use an excited and informal tone. Add a light-hearted emoji or two. The message should be no more than 280 characters. End with a question to encourage comments from fans. It works — once, but then comes the need for a shorter version, more formal version for Facebook,…  ( 4 min )

    How to Build an End-to-End MLOps Pipeline for Visual Quality Inspection
    1. Introduction Visual quality inspection is a critical process in many industrial settings, from manufacturing assembly lines to agricultural sorting. Traditionally, these inspections have relied on manual human effort or fixed rule-based machine vision systems. However, with increasing product complexity and the demand for higher throughput, these approaches often fall short in terms of accuracy, scalability, and adaptability. This is where machine learning (ML) offers a transformative solution, enabling automated, intelligent defect detection. While cloud-based ML inference is powerful, many industrial applications necessitate "edge inference." This means deploying ML models directly onto devices located close to the data source – on the factory floor, in remote facilities, or on autono…  ( 21 min )
    Scripting Limitation of Microsoft 365 F1
    Microsoft 365 F1 is tailored for frontline workers who need secure, streamlined access to essential tools without the complexity of full desktop applications. While the plan supports core communication and collaboration features like Teams and Outlook (web/mobile only), it offers limited capabilities when it comes to scripting and automation. Users on the F1 plan do not have access to full desktop versions of Office apps, which restricts the use of advanced scripting tools like VBA macros in Excel or Word. Users on Microsoft 365 F1 can access Power Automate, but only at a basic level. This means they can create simple workflows using standard connectors—such as automating approval requests or notifications via Microsoft Teams. However, premium connectors and advanced process automation are not available under this plan. Organizations that require more complex automation across apps and services will need to consider a higher-tier license to unlock those features. While end-users face scripting restrictions, IT administrators managing Microsoft 365 F1 environments do have access to some administrative scripting capabilities via PowerShell. This allows them to automate user provisioning, license management, and certain security configurations. However, these tasks are limited to what’s permissible within the F1 license scope and do not extend scripting capabilities to the end-users themselves. If your business requires users to run scripts, develop custom solutions, or build automated workflows across multiple services, Microsoft 365 F1 may not be sufficient. Plans such as Microsoft 365 Business Standard, E3, or E5 offer full desktop apps, broader access to Power Automate, Microsoft Graph API, and more advanced scripting environments. Upgrading to one of these tiers ensures your team has the flexibility and tools needed for deeper customization and process automation.  ( 3 min )
    Design Database Schemas Offline & Synchronize with DbSchema

    How to connect my hall effect sensors to my microcontroller?
    Connecting Hall effect sensors to your microcontroller (MCU) is straightforward, but depends on whether you're using a digital or analog Hall sensor. Step 1: Determine Your Sensor Type Step 2: Wiring Diagram Digital Hall Effect Sensor (e.g., A3144) Vcc: Connect to 3.3V or 5V (check sensor datasheet) GND: Ground OUT: Connect to digital GPIO input Circuit: Add a pull-up resistor (~10kΩ) between OUT and Vcc (if not already onboard). OUT will go LOW when a magnet is detected, HIGH otherwise. plaintext [ A3144 Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- GPIO (with 10kΩ pull-up to Vcc) MCU Code (Polling Example in C): c if (HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0) == GPIO_PIN_RESET) { // Magnet detected } Analog Hall Sensor (e.g., SS49E) Vcc: 3.3V or 5V GND: Ground OUT: Analog voltage (connect to ADC pin) Circuit: No pull-up needed. Output voltage is typically mid-scale (e.g., ~2.5V) when no magnetic field is present. Varies higher or lower depending on magnetic field direction and strength. plaintext [ SS49E Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- ADC pin (e.g., PA0) MCU Code (STM32 ADC Example): c uint32_t adc_val = HAL_ADC_GetValue(&hadc1); // Convert to voltage float voltage = (adc_val * 3.3) / 4095.0; Step 3: Setup in STM32CubeMX (If using STM32) Digital Sensor: Configure GPIO as input, optionally with interrupt. Analog Sensor: Enable ADC, select correct pin, and configure sampling time. Tips Check your Hall sensor's operating voltage before connecting to a 3.3V or 5V MCU. Use decoupling capacitors (0.1µF) near the sensor for noise filtering. For multiple sensors, assign each to a separate GPIO or ADC channel. Use interrupts for real-time edge detection with digital sensors.  ( 3 min )

    How JavaScript Lint Rules Work (and Why Abstract Syntax Trees Matter)
    Linting tools like ESLint have become an essential part of modern JavaScript development. They help enforce code quality, prevent bugs, and maintain consistent codebases across large teams. But few developers understand how lint rules work behind the scenes. At the core of this powerful system is a data structure known as the Abstract Syntax Tree (AST). This article will demystify lint rules by showing how they interact with ASTs, provide examples, and even demonstrate how to write your own custom lint rule using ESLint. A linter is a static code analysis tool. It scans your code without executing it, looking for issues like: Syntax errors Bad practices Style violations Code smells Security flaws Popular JavaScript linters: ESLint – Highly configurable and plugin-based.

    What should we do when SQL (and stored procedure) runs too slowly?
    As the most commonly used data processing language, SQL is widely used in many scenarios, such as query and batch operating. When the amount of data is large, SQL (and stored procedure) often leads to very slow running. In this case, it needs to optimize SQL. To optimize SQL, there are some specific systemized ways. Normally, we need to check the execution plan first to find out the reason, and then recode in a targeted manner to achieve the purpose of optimization. For example, for the judgment of continuous numbers, we can use between to replace in, use the select statement to specify the field name, use union all to replace union, and rewrite exists into join. Of course, some optimization methods are available in practice, such as creating an index, and using temporary table/aggregation…  ( 13 min )

    ALTER TABLE ADD COLUMN in SQL: Syntax, Tips & Tools
    Changing your schema is part of everyday development, and ALTER TABLE ADD COLUMN is the go-to command for doing it in SQL. Whether you’re using PostgreSQL, MySQL, Oracle, or SQL Server, this command helps you evolve your tables without losing data. Here's how it works—and how to do it right. PostgreSQL/MySQL ALTER TABLE orders ADD COLUMN status VARCHAR(50); SQL Server ALTER TABLE orders ADD status VARCHAR(50); Oracle ALTER TABLE orders ADD (status VARCHAR2(50)); Define constraints from day one ALTER TABLE employees ADD COLUMN start_date DATE NOT NULL; Use meaningful names ALTER TABLE inventory ADD COLUMN last_checked DATE; Set defaults wisely ALTER TABLE tickets ADD COLUMN priority VARCHAR(10) DEFAULT 'normal'; Don’t add unnecessary columns—normalize instead. Update app logic immediately to reflect schema changes. Avoid blocking queries in production environments. Tracking reviews on a product table: ALTER TABLE products ADD COLUMN review_count INT DEFAULT 0; Keeps your schema clean while adding a useful feature. Not a fan of raw SQL? Find your table Click “Alter Table” Add your column Preview SQL Click “Execute” It’s that simple in DbVisualizer. Yes, using ALTER TABLE ... DROP COLUMN ... Use UPDATE to fill new columns with calculated values. Some do. PostgreSQL, yes. MySQL, not always. ALTER TABLE ADD COLUMN is more than just a syntax trick—it’s a key part of adapting to change. Use it wisely, document your updates, and lean on tools like DbVisualizer when needed.

    RPC Call? Clearly Explained
    In the intricate world of distributed computing, where applications are often spread across multiple machines, sometimes continents apart, the ability for these disparate components to communicate seamlessly is paramount. This is where the concept of a Remote Procedure Call, or RPC, comes into play. At its core, RPC is a powerful mechanism that allows a program on one computer to execute a procedure (a subroutine or function) in another program located on a different computer, or even in a different address space on the same computer, as if it were a local call. This abstraction simplifies the development of distributed applications by hiding the underlying complexities of network communication. Imagine you're a chef in a busy kitchen (your local program).

    When Code Meets Candles: What Trading Taught Me About Systems and Mindset
    As a developer in the past, I’ve always been drawn to systems — clean logic, predictable outcomes, elegant solutions. But trading? Trading is the exact opposite. It’s messy, unpredictable, and deeply human. At first, I tried to approach the market like I do software — build a strategy, test it, automate where possible. But the markets don’t run on code alone. They run on psychology, emotion, global events, and a thousand invisible threads. That clash between logic and chaos forced me to rethink everything I thought I knew about building systems. Trading isn’t just about algorithms or signals. It’s about mindset, discipline, and adapting your approach when the unexpected hits. Over time, I learned to treat my trading strategy like I do a project: start with a clear structure, iterate fast, test assumptions, and most importantly — expect the system to fail sometimes. It’s a humbling process. But it’s also one that makes you better, not just as a trader, but as a developer and thinker.  ( 3 min )

    Destructor in python
    A destructor (del) is used to clean up resources when an object is about to be destroyed. It doesn't run immediately after an object is no longer used, but is triggered automatically by Python's garbage collector when there are no more references to that object. Important Points: Python automatically calls the destructor (del) When no more variables reference an object, Python automatically calls del() (if defined). When is del() useful? You might define a destructor when: You need to close a file. You don’t manage memory directly (like in C/C++). Python handles memory. You can’t force the garbage collector to run at an exact time (though you can suggest it using gc.collect()). 🧠 Analogy It watches which objects you're using. When you stop using something and forget it, the housekeeper eventually throws it out. If you say del obj, you're telling the housekeeper: "Hey, I don't need this anymore." But the housekeeper decides when to actually throw it out.  ( 3 min )

    Understanding Stale Closures in React: Common Pitfalls and How to Avoid Them
    🧠 1. Overview of Stale Closure in React In React, a common but subtle bug is the "stale closure" — which happens when a function inside a component uses an outdated value, not reflecting the current state or props. This often leads to unexpected behavior, especially in callbacks, useEffect, or asynchronous logic. Understanding how JavaScript creates closures and how React handles re-renders is key to avoiding this issue. Scope defines the visibility of variables. In JavaScript, we have function scope and block scope. A closure occurs when a function remembers variables from the scope where it was defined, even if it's executed elsewhere. Example: function outer() { let count = 0; return function inner() { console.log(count); // closure retains the value of count }; } Closure…  ( 4 min )
    Sleep Mode: Automating Wi-Fi & Bluetooth Off at Night on Apple Devices
    As a runner and fitness enthusiast, sleep is essential for my recovery — and yet, it’s something I’m constantly working to improve. I aim for 8 hours a night, but my Apple Watch reports an average closer to 6.5 hours over the past few months, with some nights dipping as low as 5. Being a light sleeper doesn’t help either. I’ve experimented with wax earplugs to block out noise and blackout curtains to keep light at bay. One thing I’ve wanted to automate for a while now is disabling Wi-Fi and Bluetooth on the devices near my bed — including both my personal and work MacBooks, my iPhone, and ideally even my Apple Watch (which I wear to track sleep). These devices all stay in my bedroom overnight, so minimizing potential sleep disruptors has become a personal experiment. You might ask: why go …  ( 7 min )

    How Do You Stay Motivated When Coding Gets Tough?
    We’ve all been there staring at a stubborn bug or feeling completely stuck on a complex problem. When coding gets frustrating, how do you move forward? For me, breaking a problem down into smaller steps and focusing on one thing at a time really helps. I also take short breaks to clear my head and come back with fresh eyes. Sometimes, just going for a walk makes a big difference. I try to remind myself why I started coding in the first place, it’s easy to lose sight of that when things get tough. What about you?

    noOp variable in n8n source code.
    In this article, we review a variable named noOp. This is something I found in logger.ts file in the n8n source code. When I saw this line below, what it tells me straight away is that it’s something to do with no operation : const noOp = () => {}; When you look at this, it’s doing nothing. I mean, it’s just an arrow function that returns an empty object So you might be wondering how is this used? So that’s what we will find out. When I click on the no-op, these are the symbols I found on the right side and in the same file, I see that this variable is used at line 103. When I click and jump to that line, you will see that this is inside a function called setLevel. private setLevel() { const { levels } = this.internalLogger; for (const logLevel of LOG_LEVELS) { if (levels[logLe…  ( 5 min )
    Safari's Tab Key Trap: Why Your Website's Focus Navigation Might Be Breaking for Safari Users
    Recently, a zk user reported that they couldn't tab through all interactive elements on a zul page. This behavior is tied to a little-known setting deep in Safari’s Settings. Keyboard navigation is essential for accessibility, allowing users who rely on keyboards or assistive technologies to navigate without a mouse. It also benefits power users who prefer using Tab for faster navigation. If this doesn't work as expected, especially on Safari — one of the major browsers — it can be a frustrating and invisible blocker. Assuming I create a page with a textbox, menubar, menuitem, anchor link, intbox, navbar, and navitem, and visit it with various browsers. When pressing the Tab key in Chrome (136.0), Firefox (138.0), and Edge (136.0), I can successfully move through all components, including each link, menu item, and nav item. But within Safari (18.4), I can only focus on some components. Safari will skip most menu items, links, and nav items. You can try the page on zk fiddle with your Safari. I found the root cause is: The option “Press Tab to highlight each item on a webpage” in Safari Settings is unchecked by default. After I checked that option, I can focus on all components by pressing the Tab key. If it’s unchecked, you have to press Option + Tab key to focus on all components.  ( 3 min )
    Rethinking API Versioning: Why Full Semantic Versioning Might Be an Anti-Pattern for Your API
    API versioning is an indispensable discipline in the lifecycle of any application programming interface. As APIs evolve with new features, bug fixes, or fundamental architectural changes, a robust versioning strategy is paramount to ensure smooth transitions for client applications and maintain a stable ecosystem. Many development teams, drawing from their experience with software libraries, naturally gravitate towards semantic versioning (SemVer), a widely adopted standard that uses a three-part MAJOR.MINOR.PATCH numbering scheme. However, while SemVer offers undeniable clarity for software packages, its direct and granular application to version REST API endpoints can introduce unnecessary complexity, operational overhead, and a less-than-ideal experience for API consumers.

    RAG: Smarter AI Agents [Part 2]
    Most developers who works with AI eventually hit the same wall - context. You can pipe tools together, chain AI prompts, or write clever workflows, but at some point, you realize your agent isn’t really thinking. It’s reacting. You need something different. I hope you used n8n, LangChain, or a similar tool, and you probably created pipelines where each AI step feeds the next. That works for formatting data or guiding workflows. And it is fine for simple agents, but what if your agent needs to remember? What if it needs to learn across conversations? How about adapt to changes? ... or retrieve knowledge like a human? Before diving into the code, let’s break down AI memory into three simple categories: Stateless (No Memory): Short-Term Memory: Long-Term Memory: try to remember remembers prev…  ( 5 min )
    How I Built an AWS Project Idea Generator Using AI
    As someone who constantly learns and writes about AWS, I’ve found myself often asking: “What should I build next?” Not just for the sake of learning—but to challenge myself, grow professionally, and create blog posts that actually help others. But here’s the thing… coming up with project ideas is hard. With over 200 AWS services, it’s easy to feel overwhelmed. I’d often sit down thinking: Should I build something with Lambda? Maybe try a serverless ETL pipeline? What’s a good way to combine AI and AWS? But instead of starting, I’d spiral into: Paralysis by analysis. It turns out I wasn’t alone. Many AWS learners and professionals face the same challenge. That’s when an idea struck: What if I could describe: My experience level The AWS services I want to learn or showcase ...and an AI c…  ( 5 min )

Traditionally, personalized content is generated at runtime by backend services. This often involves API calls, session validation, user segmentation, and rendering logic.…  ( 5 min )
    📢 Amazon RDS Now Supports Easy Retrieval of Engine Lifecycle Support Dates
    Managing the lifecycle of your Amazon RDS databases just got easier! Amazon RDS now provides a simple way to view engine support dates for your database engines — directly from the RDS API or AWS CLI. With this new feature, you can now: ✅ View start and end dates for RDS Standard Support ✅ Check if RDS Extended Support is available ✅ Get both support periods in a single response (if available) This applies to Amazon RDS and Amazon Aurora major engine versions. Previously, finding out when your database engine version would reach its end of support meant digging through documentation or announcements. Now, you can fetch this information programmatically, making it easier to: 🗓️ Plan upgrades ahead of time 🛡️ Ensure compliance and security 🚫 Avoid running unsupported versions Here’s how you can check support dates for PostgreSQL 11: aws rds describe-db-engine-versions \ --engine postgres \ --engine-version 11 \ --include-all Output (simplified): { "Engine": "postgres", "EngineVersion": "11", "SupportDescription": { "StandardSupport": { "StartDate": "2018-10-01", "EndDate": "2024-11-09" }, "ExtendedSupport": { "EndDate": "2026-11-09" } } } Now you know exactly when your engine support ends — and whether Extended Support is an option. This feature is a great step toward proactive database lifecycle management. If you're running critical workloads on Amazon RDS or Aurora, this new visibility helps ensure business continuity, security, and compliance. ➡️ Start using it today with the AWS CLI or API! Let me know what you think about this new feature. Are you planning to use it to manage your DB upgrades better?  ( 4 min )

    Why is my React component flickering?
    Understanding Re-renders with React Context and how to avoid waste Have you ever wondered why your component in React re-renders even without anything visibly changing? Let's understand this with simple examples – as if we were assembling a block game. Imagine three components, one inside the other: And let's say you have a Context at the top (App) that shares some data with everyone below. If re-renders (for any reason), all components below it also re-render: App -> Container -> SearchContainer -> Search Even if only the last one (Search) actually uses the Context! If Container and SearchContainer don't need to change, we can avoid the effort of re-rendering them by using…  ( 5 min )

    🧼 How to Write Clean React Code
    Writing clean code in React is not just about making it work—it's about making it readable, maintainable, and scalable. Whether you’re building a simple to-do app or a large-scale application, following clean code principles will make your life (and your team’s) much easier. Here are some practical tips to help you write clean React code 👇 📁 Organize Your Folder Structure Structure your project in a scalable way. Avoid dumping all files in one folder. Bad: /src Good : 🧩 Use Functional Components & Hooks Prefer functional components with hooks over class components. // ✅ Clean function Welcome({ name }) { return Hello, {name}! ; } 📦 Break Components into Smaller Pieces Keep components small and focused on one task. If a component is doing too much, break it into smaller ones. // ❌ Bad const Dashboard = () => { // fetching, rendering UI, handling logic... all in one }; // ✅ Good // Dashboard.jsx → uses , , etc. 🧹 Clean Up useEffect Always clean up side effects to avoid memory leaks. useEffect(() => { const interval = setInterval(() => { console.log("Running..."); }, 1000); return () => clearInterval(interval); // ✅ cleanup }, []); 🧪 Write Reusable Hooks Extract reusable logic into custom hooks. // useToggle.js import { useState } from 'react'; export function useToggle(initialValue = false) { const [state, setState] = useState(initialValue); const toggle = () => setState(prev => !prev); return [state, toggle]; } 🚀 Final Thoughts Easy to read 👓 Easy to reuse ♻️ Easy to test 🧪 Easy to maintain 🛠️ You don’t need to be perfect—just aim for improvement step by step.

    Never lose valuable error context in JavaScript
    If you are a JavaScript developer, you might have ran into error messages like: Failed to extract text from the file Failed to save entity And so on... But what exactly led to failing of an entire high-level operation? We don't know the answer because we didn't do a good enough job to preserve the error context, when throwing a specific error that is a symptom of a more low level cause. For years, JavaScript developers have struggled to preserve appropriate error context when throwing exceptions, as there was no in-built mechanism provided by the language to attach error cause, unlike other languages like Java, Python and C#. This problem was solved by Node, when they finally added a cause property to their Error constructor in v16.9.0, which means you could now throw exceptions like so: t…  ( 5 min )

    Capstone notes p2
    Writing sample data: started with small amount from Study Buddy - need to follow "Contact Book - Our Very First Database" from AppDev1 section "custom rake tasks" Association Accessors: Direct Associations: belongs_to default is opposite: belongs_to adds an automatic validation to foreign key columns enforcing the presence of a valid value unless you explicitly add the option optional: true. So: if you decided to remove the null: false database constraint from any of your foreign key columns in the migration file (e.g., change t.references :recipient, null: false ... to t.references :recipient, null: true ...), then you should also add the optional: true option to the corresponding belongs_to association accessor. So remember — if you’re ever in the situation of: you’re trying to save a record the save is failing you’re doing the standard debugging technique of printing out zebra.errors.full_messages you’re seeing an inexplicable validation error message saying that a foreign key column is blank now you know where the validation is coming from: belongs_to adds it automatically so figure out why you’re not providing a valid foreign key (usually it is because the parent object failed to save for its own validation reasons) Direct associations: has_many belongs_to, there should be an inverse has_many.

    How To Introduce a New API Quickly Using Quarkus and ChatGPT
    My last two articles (part 1 and part 2) focused on getting to market quickly using Java. The only difference was the build automation tool that I used for each example. This time, I want to step outside of my comfort zone and try something a little different.

    React Mastery: Understanding `onChange={handleChange}` vs `onChange={(e) => handleChange(e)}`
    onChange={handleChange} vs onChange={(e) => handleChange(e)} In modern React development, handling events is a foundational skill for building responsive, data-driven interfaces. Whether you’re crafting a dynamic form or building reusable components, knowing how to manage events efficiently can make your code simpler, more readable, and more performant. Today, we’ll break down a deceptively simple difference that many React devs gloss over: onChange={handleChange} vs onChange={(e) => handleChange(e)} At first glance, both seem to do the same thing—pass the event to a handler. But there are subtle differences that matter in real-world apps. Let's explore them together.

    US tourist drugged by fake Uber driver and robbed of $123K BTC — Report
    An American tourist in the United Kingdom was reportedly drugged by an individual posing as a taxi driver, who stole the tourist's $123,000 in Bitcoin stored on a cell phone. According to a report from My London, Jacob Irwin-Cline went out to a London bar and had several drinks before calling an Uber to take him home. Cline said that he did not thoroughly check the details of the Uber ride on his phone and left with a random private cab driver resembling the Uber driver at first glance, but driving a different vehicle — a detail Cline would only discover after the incident. Once inside the vehicle, the US tourist said the driver offered him a cigarette, which Cline said was likely laced with a rare and potent sedative drug called scopolamine. Cline added that the cigarette made him feel …
    Senators plan to amend GENIUS Act to address Trump family's stablecoin
    Though a majority of members of the US Senate voted to advance a bill to regulate payment stablecoins on May 20, high-ranking Democrats are planning to propose an amendment to the legislation to address President Donald Trump’s connections to the cryptocurrency industry. According to a May 22 Axios report, Senate Minority Leader Chuck Schumer and Senators Elizabeth Warren and Jeff Merkley will file an amendment to the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, to block a US president from profiting from stablecoins. The proposed amendment would come after 18 Democrats sided with Republicans in the Senate in voting to advance the bill on May 20 after it failed a procedural vote on May 8. “Passing the GENIUS Act without our anti-corruption amendment s…
    XRP price fails to respond to two extremely bullish developments — Here is why
    Key takeaways: The SEC’s decision on a spot XRP ETF could ignite a significant rally. The current $2.2 billion in XRP futures hints at growing institutional investor demand. The two most bullish events ever imagined by XRP (XRP) advocates happened in 2025, but XRP continues to underperform the cryptocurrency market.

According to the Cetus team, the DEX is working with the Sui Foundation and other entities within the ecosystem to recover the remainder of the funds. The Sui Foundation also confirmed: "A large number of validators identified the addresses with the stolen funds and are ignoring transactions on those addresses until further notice.

    OpenAI plans to ship 100 million pocket-sized AI devices for everyday use
    OpenAI is planning to develop AI “companion” devices that will integrate artificial intelligence capabilities with everyday life, potentially opening the door to a new high-tech innovation used alongside laptops and smartphones. In an interview with The Wall Street Journal, OpenAI CEO Sam Altman said he and designer Jony Ive are developing these secret devices for mass consumption, with plans to ship 100 million units upon launch. Ives joined OpenAI after his startup, io, was acquired by Altman’s company in a $6.5 billion deal, the Journal reported on May 21.  Neither Altman nor Ives specified what these companion devices would look like or how they would operate. Ives simply referred to them as a “new design movement” that would be similar to Apple’s family of hardware and software integr…
    Solana price fractal targets rally to $260, but one thing must happen first — Analysts
    Key takeaways: Solana’s bull flag pattern projects a rally to $260, but low spot buy volumes have analysts advising caution. After briefly dropping to $160 from $184, Solana (SOL) is attempting to reclaim a position above its key resistance at $180 for a second consecutive week. With Bitcoin (BTC) hitting an all-time high, market speculators are banking on eventual capital rotation, which could pump major altcoins like SOL toward new highs. Solana shows promising signs on the daily chart, forming a textbook bull flag pattern after a strong uptrend. While SOL prices currently trade under $180, a breakout above this level could propel SOL toward its first target at $200, with further upside potential to $220 if momentum sustains.

Tokens representing the stocks will be stored on the Solana blockchain due to its “unmatched performance, low latency and thriving global ecosystem,” the statement said. “The whole point of crypto is that we're able to see things very transparently,” Kraken co-CEO Arjun Sethi said during Solana's Accelerate event on May 22. ”It's decentralized.

    US lawmaker introduces anti-corruption bill ahead of Trump's dinner
    California Representative Maxine Waters, ranking member of the US House Financial Services Committee, has announced plans to introduce legislation “to block [Donald] Trump’s memecoin and stop his crypto corruption.” In a May 22 notice, Rep. Waters said the Stop Trading, Retention, and Unfair Market Payoffs (TRUMP) in Crypto Act of 2025 bill would be aimed at blocking the US President, Vice President, members of Congress, and their families from engaging in “crypto crime.” The US lawmaker referred to Trump and his wife, Melania, issuing personal memecoins in January, his family launching a stablecoin, USD1, through the crypto platform World Liberty Financial, and the president attempting to establish a national Bitcoin (BTC) reserve as his sons back a BTC mining venture. “Donald Trump is preparing to dine with the top donors of his memecoin who’ve made him, and his family, richer,” said Waters, adding: “Trump’s crypto con is not just a scam to target investors. It’s also a dangerous backdoor for selling influence over American policies to the highest foreign bidder.” HR 3573, Stop TRUMP in Crypto Act of 2025, introduced by Rep. Maxine Waters. Source: House Financial Services Committee Democrats Waters’ bill was one of many actions announced to oppose the president’s dinner to reward memecoin holders.

    BTC price eyes $112K as risk assets 'ignore bad news' on unemployment
    Key points: Mixed results for US jobless claims fail to dent risk-asset enthusiasm.

    Bitcoin could go much higher due to lack of FOMO and futures market euphoria — Analysts
    Key takeaways: Bitcoin’s rally to new price highs happened as funding rates and trading sentiment remained unusually subdued. Rising stablecoin supply and global M2 growth indicate untapped liquidity and the potential for further price increases. Long-term holders are not aggressively selling, reflecting their expectation for continued Bitcoin price appreciation. Bitcoin (BTC) hit a new all-time high on May 21, with prices rising to $111,860 on Binance on May 22, but the markets lack the state of frenzy associated with new highs.

    Semiconductor exemptions don’t matter when it comes to tariffs
    Opinion by: Ahmad Shadid of O.xyz Semiconductors scored a rare exemption from US President Donald Trump’s aggressive reciprocal tariffs, but the relief is symbolic at best. Most semiconductors enter the US embedded in servers, GPUs, laptops, and smartphones.  The finished goods remain heavily tariffed, some with duties reaching up to 49%. The exemption looks good politically but delivers little practical benefit. Nvidia’s DGX systems, crucial for training advanced AI models, do not fall under the exempted HTS codes. Nvidia could pay effective tariffs nearing 40% on these vital components. Such costs threaten to stall critical AI infrastructure projects across the country.  Semiconductor tariffs may compromise the goal of the CHIPS Act. The act promised tens of billions of dollars in subsid…
    Which senators invest in crypto? 11 lawmakers have blockchain-related investments
    As the question of stablecoin regulation heats up in the US Senate, so has the issue of which members are personally invested in cryptocurrencies and cryptocurrency firms. On May 19, the Senate voted to invoke cloture and move ahead with the GENIUS Act, which would provide a regulatory framework for stablecoins. The measure passed 66-32, with 16 Democrats supporting the bill. Democratic concerns over corruption and politicians’ ties to cryptocurrency firms made the bipartisan move controversial. After the vote was finished, Colorado Senator Michael Bennet introduced the STABLE GENIUS Act. The bill would prevent members of Congress from issuing or investing in digital currency and require them to put their crypto in a blind trust while in office.

    Exponential currency debasement: ‘You don’t own enough crypto, NFTs’
    Cryptocurrencies and non-fungible tokens (NFTs) can help investors protect their eroding purchasing power during an era of exponential currency debasement, according to analysts and industry leaders. Investing in digital assets is becoming increasingly important in the “world of the exponential age and currency debasement,” according to Raoul Pal, founder and CEO of Global Macro Investor. “You don’t own enough crypto. When you do, you don’t own enough NFT’s, as art is upstream of wealth. Both will never be this cheap again,” Pal said. NFTs are “the single best long term store of wealth I know and you get to buy it before network effects kick in,” he added in another response.

    How staking incentivizes trust without burning energy
    What if a financial system could run itself not by burning electricity, but by rewarding good behavior? That’s the promise of staking, a mechanism that powers many modern blockchains by turning users into network operators.  In this week’s episode of The Clear Crypto Podcast, hosts Gareth Jenkinson and Nathan Jeffay sit down with StarkWare’s Noam Nisan to unpack how this trustless engine works, why it matters and what’s really at stake. Understanding staking Jeffay began by highlighting how staking is part of the backbone that keeps the blockchain running, and runs itself, with volunteers. “By doing this, they’re saying, OK, we’re taking this task of running the blockchain seriously. Here's some of our money. We're putting it down. We're showing that we're serious about doing this.” To he…

    UK court partially dismisses Bitcoin SV investor’s lawsuit against Binance
    The United Kingdom’s Court of Appeal partially dismissed a lawsuit brought by Bitcoin SV investors against major crypto exchanges, including Binance, for allegedly conspiring to delist the token in 2019. In a judgment handed down on May 21, the court ruled that investors who held BSV through the delisting period (classified as “sub-class B”) were not entitled to billions in speculative damages based on BSV’s hypothetical growth. These investors had claimed over 8.9 billion British pounds ($11.9 billion) in damages, asserting that Binance’s delisting deprived holders of the chance to profit from BSV’s potential rise to a “top-tier cryptocurrency” like Bitcoin (BTC) or Bitcoin Cash (BCH). The court rejected this “foregone growth effect” theory, stating, “BSV was obviously not a unique crypto…

    Whale buys back ETH holdings after losing $2.67M by selling early
    A crypto trader spent $3.8 million to buy Ether at a significantly higher price after selling the asset for almost the same amount about a month ago.  On May 22, blockchain analytics firm Lookonchain reported that a crypto wallet spent $3.8 million to purchase 1,425 Ether (ETH) at $2,670 per coin, reentering ETH after a major rally.  On April 13, the same wallet sold 2,522 ETH for $3.9 million, when the asset was trading at about $1,570, a decision that, in retrospect, looks poorly timed.  “Think twice before selling your bags,” Lookonchain wrote, highlighting the potential gains if the trader just held on to their Ether instead of selling and repurchasing it at a higher price point.  Whale buys ETH after selling over a month ago.

    Can ChatGPT-powered AI agents really trade crypto for you?
    Key takeaways ChatGPT-powered AI agents automate trading tasks using natural language prompts and API integrations, improving speed and consistency. Successes occur when ChatGPT is used as a support tool, not a fully autonomous trading system. Failures happen when traders over-rely on ChatGPT without real-time data, proper risk management or manual oversight. Regulatory focus on AI in trading is increasing, with new frameworks emerging to ensure transparency, accountability and compliance.

    Trump’s crypto czar David Sacks says stablecoin bill is ‘going to pass’

The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act is the most advanced federal effort yet to establish a legal framework for dollar-pegged digital assets.

    5 red flags you’re being shilled: Don’t buy the hype
    What is shilling in crypto? At its core, shilling is the act of artificially promoting a cryptocurrency or token, often with exaggerated claims, to increase its price or popularity.  But what’s the goal?  Hype it up, get others to buy in, and then cash out, leaving latecomers holding the bag. Shilling can come from anyone: influencers, anonymous accounts or even high-profile figures with political or financial clout. The common thread is manipulation: It’s not about educating you or building real value but pumping hype for personal gain. Unfortunately, the line between enthusiastic promotion and outright deception can be thin, and many fall victim without realizing it. That’s why it’s critical to learn how to spot the signs early. …

In one day alone, IBIT has accumulated over 10 times the amount of Bitcoin (BTC) mined over the same timeframe, with it scooping up 4,931 BTC against just 450 BTC produced for the day. IBIT also saw its largest volume day since January, according to the ETF tracking X account Trader T.  “Given trading volume today, expect these inflow numbers to increase,” said ETF Store president Nate Geraci.  Bl…
    Synthetix scuttles $27M Derive deal after community concerns
    Decentralized finance platform Synthetix has axed its $27 million plan to acquire crypto options platform Derive after negative community feedback. A Synthetix spokesperson told Cointelegraph on May 22 that its acquisition proposal, pitched to its community and to Derive’s, “did not resonate,” and both projects agreed to “step back from the proposed acquisition.” Synthetix said on May 14 that it would acquire Derive in a token exchange deal, pricing 1 SNX token to 27 DRV tokens, which would value Derive at around $27 million, pending approval from both communities.  Synthetix strategy lead Ben Celermajer told Cointelegraph that other community concerns were the three-month token lock-up period and the deal’s price, part of which Synthetix tried to address with no lock-up for holders of les…
    Bitcoin continues rally to surpass $110K for the first time
    Bitcoin has topped $110,000 for the first time in a recent rally that has seen it gain 3% over the past day to break through past price highs from earlier this year. Bitcoin (BTC) hit a new all-time high of $110,788.98 on Coinbase late on May 21, just before 11:30 pm UTC, according to TradingView. Bitcoin has gained around 3% over the last 24 hours, surpassing its all-time high of $109,458 that it hit earlier in the day, which was the first time it traded above its previously long-held Jan. 20 peak. The world’s largest cryptocurrency has now gained 17.5% so far this year and is up 47% since its slump to $75,000 on April 7, triggered by US President Donald Trump enacting sweeping tariffs that tanked global markets. Bitcoin’s new peak comes as US stock markets were rattled by a weak 20-year …

    Australian regulator asks High Court to allow appeal in Block Earner case
    Australia’s financial regulator will seek the High Court’s permission to appeal a lower court’s ruling favoring fintech firm Block Earner, which found the company’s crypto-linked fixed-yield earning service is not a financial product. The Australian Securities and Investment Commission (ASIC) said on May 21 that it wants to ask the High Court of Australia to clarify what the definition of a financial product is and clarify the circumstances when an interest-earning product and conversion of assets from one form to another are regulated. “The definition of financial product was drafted in a broad and technology-neutral way, and ASIC believes it is in the public interest to clarify this,” the watchdog said. “This clarification is important as it applies to all financial products and services…

    Rising Beyond Routine
    For years, IT professionals have balanced a critical dichotomy: essential yet monotonous daily tasks consuming their valuable expertise. Microsoft's bold integration of artificial intelligence within Microsoft 365 challenges—and changes—this paradigm entirely. As AI quietly assumes the ordinary, IT admins can step forward into the extraordinary, shifting from managing minutiae to shaping strategy. What happens to an IT admin freed from repetitive chores? They're empowered to innovate, wield influence, and transform their role from problem-solvers into organisational visionaries. Imagine—just for a moment—a day without countless clicks, portal navigation, or routine queries. Imagine speaking naturally to your administrative tools, eliciting immediate insights and seamless summaries. Enter M…  ( 6 min )
    readonly vs disabled in Rails Forms
    Today I found out that disabling a form field in Rails means it won't be submitted at all. I used disabled: true thinking I could show a value that users can’t change — and I could — but the downside is that the value doesn’t get sent to the controller. I learned that if I want the value to be shown but not editable and still be passed in the form data, the correct attribute to use is readonly: true. This small difference between disabled and readonly matters when you're depending on that data in your controller. It’s not a Rails issue; it’s how forms work in general. This was a helpful thing to learn today. Hopefully it saves someone else a bit of time too.  ( 3 min )

    Machine Learning 101
    In very simple terms, Machine Learning is the process of using existing data to create a mathematical function. For example, we have an ice cream shop's data that includes the average temperature of the past 30 days, along with the number of ice creams sold on each day. We can analyze this data (average temperature and number of ice creams sold) and can create a mathematical function that fits with the existing data. Further, this function can take the average temperature as input and return the prediction of the number of ice creams that can be sold on that day. From the existing data, the data that we use as the condition, in our case, the average temperature, is called a Feature. The main data that we are targeting to predict, in our case, the number of ice creams sold, is called the Label (also known as the target variable in technical terms). In mathematical terms, the features are referred using xxx . Hence, the features can be represented as [ x1,x2,x3,...,xnx_1, x_2, x_3, ..., x_nx1​,x2​,x3​,...,xn​ ]; whereas the label is referred to as yyy . The process of defining the function using the existing data is called Training. This is the step where the model (a general term used for the mathematical function we create) learns the relationship between features and labels. Further, the process of using the defined function to get the predicted value is called Inferencing. In mathematical terms, the function is referred to as f(x)f(x)f(x) . Moreover, the predicted value by the function is referred to as y^=f(x)\hat{y} = f(x)y^​=f(x) Final Words This was the fundamental knowledge of Machine Learning.  ( 3 min )
    Stop Using `console.log` — These Debugging Tricks Will Blow Your Mind
    Let’s face it: console.log is the comfort food of debugging. It’s quick, familiar, and kind of satisfying in that junk-food sort of way.

    What’s the Real Difference Between Freestyle and Pipeline Jobs in Jenkins? Here’s What I Learned
    When I first started using Jenkins, I began with Freestyle jobs, which felt straightforward—just click, configure, and run. Then I explored Pipelines and learned how they differ by building a Java app, scripting from the terminal, and using Git to manage project files. 1. Building with Freestyle Jobs Build my Java app using Maven Run shell scripts (after configuring Jenkins to recognize Git Bash) Understand that the pom.xml file is essential for Maven builds because it defines the project structure and dependencies Freestyle jobs provide an easy way to experiment, but there are limitations when the build process becomes more complex. 2. Exploring Pipelines – Defining Builds as Code Pipeline jobs allow defining every build step as code within a Jenkinsfile. Instead of using the UI, the process is scripted, for example: pipeline { agent any stages { stage('Build') { steps { echo 'Running build...' } } } } This approach enables version control of build processes, clearer visibility into each stage, and better scalability for complex workflows.  ( 3 min )
    Organizational Design – Structures & Human Behaviour
    An organization’s structure determines how people communicate, make decisions, and stay motivated. Groups employees by specialized functions (e.g., Marketing, Finance). Pros: Deep expertise within departments Clear career paths and supervision Cons: Silos may form, limiting collaboration Slow decision-making across functions Organizes units around products, markets, or regions. Pros: Strong focus on specific product lines or geographies Faster response to local needs Cons: Resource duplication across divisions Potential competition for corporate support Combines functional and divisional chains of command. Pros: Flexible deployment of talent Encourages cross-functional teamwork Cons: Dual reporting can confuse roles Political jockeying for scarce resources Centers on a small core organization that outsources major functions. Pros: Highly adaptable to change Leverages external experts Cons: Less direct control over partners Dependency on external stability 5. Team-Based Structure Organizes around self-managed, cross-functional teams. Pros: High employee engagement and ownership Rapid innovation through diverse perspectives Cons: Role ambiguity can arise Requires strong team-building and conflict-management skills How Structure Shapes Behavior • Communication: Hierarchies vs. networks change how information flows. • Decision-Making: Centralized vs. decentralized structures affect speed and empowerment. • Motivation: Clear roles boost certainty, while fluid teams drive creativity.  ( 3 min )
    Understanding Activity Lifecycle on Android Apps
    In android applications, the programs and screens which users can interact are presented by activity. Every application have at least one activity, but not limited to one. There are several lifecycle process of activity: All of these lifecycle of activities are having their own callback methods, to run certain functions when they are reaching certain state: Activity First Created Initialization and basic setup of the activity you also need to call what layout to be served to UI Activity becoming visible to user User are able to see the activity, but not yet responsive for user interaction Preparation before becoming interactive Activity starts interacting with user For example, when you gets called when using your phone and you answer the call, after the call it will give you the resume Captures user input, usually where the implementations of app core's functionality is done This First 3 callback function will be created and called when open app System changed focus from the current activity For example, when you use application and open another app, onPause() will be called. Application still partially visible. Indicate activity to enter either stop or resume Activity is no longer visible to user Activity is destroyed usually used for clean up Activity is stopped and is starting again always followed by onStart() activity-lifecycle by developer android what is activity in android  ( 3 min )

    Daily Quantum Learning #13 — Josephson Junctions
    Step 1: Understand Superconductivity What’s Superconductivity? At super low temperatures, certain materials like niobium or aluminum lose all electrical resistance, becoming superconductors. Electrons pair up into Cooper pairs, moving through the material without losing energy. Why This Matters: Superconductivity allows quantum effects, like tunneling, to take place without interference from electrical resistance. This sets the stage for a Josephson junction. Think of It Like: A frictionless highway where cars (electrons in this case) can zoom along without slowing down. Step 2: Build the Josephson Junction Structure: A Josephson junction is made by sandwiching a super thin insulating layer (like aluminum oxide, just a few nanometers thick) between two superconducting materials (e.g., niob…  ( 4 min )

    BeaconAI: a Fun AI Project (Built with GPT, ElevenLabs, Replicate & More)
    It started from the idea that it would be cool to have an automatically generated "zen koan" play out at a specified interval, automatically generated using prompt-engineering to created varied outputs. For example, every hour between 8AM and 8PM, I would call the API with a prompt like "Inspire me with amazing life energy and tie in _____" and the blank would be filled in with a random word or phrase so that each generation was fresh. Then this would be turned into audio with TTS and played through the speakers. This was just the basic idea, and I quickly began building this using Python scripting and ample help from GPT to accelerate the process. Quickly I realized it would be more fun to make it a creative app, and ideas began to flow. Eventually it became more to my taste as an artisti…  ( 10 min )

    The Ultimate YAML Guide for Developers: From Basics to Advanced DevOps Workflows
    Introduction YAML (YAML Ain’t Markup Language) is a human-readable data serialization language designed for configuration and data interchange. Unlike XML or JSON, YAML uses minimal syntax and indentation (spaces) to represent structure, making it easy for humans to read and write. Developers encounter YAML all the time: it’s the backbone of many DevOps tools (Kubernetes manifests, Docker Compose files, Ansible playbooks, CI/CD pipelines, GitHub Actions workflows, etc.). For instance, GitHub Actions workflows are defined in YAML files (in .github/workflows/), since “YAML is a markup language that’s commonly used for configuration files”. Because of its ubiquity in modern tooling and its focus on readability, understanding YAML is invaluable for developers. YAML’s syntax is defined by a …  ( 9 min )
    The Story That Made Me Build Cipherwill
    i started it because one day i read this weirdly simple, sad story online. a guy passed away - just some normal crypto/creator dude - and his family couldn’t access anything. no logins. no wallets. no passwords. gone. millions lost. digital accounts just... locked in time. that stuck with me way more than i expected. i kept thinking: if i died today, would anyone know how to get into my stuff and recover all crypto that i stacked on different platforms? probably not. and that’s not because i have millions (i wish), but because our lives are so deeply tied to digital accounts now. everything from money to memories is behind a login screen. and yet - no one talks about what happens to it all when we're gone. so that’s where cipherwill came from. a simple thought: what if there was a way to s…  ( 4 min )
    The easiest way to connect your .NET app to Gemini using MaIN.NET.

    The Tiny Cat Guide to AI #2: Generative AI – What's Inside the Magic Box?
    Welcome back to The Tiny Cat Guide to AI! In our previous post on Prompt Engineering, we explored how to give clear instructions to our creative AI felines. 😹 Now, let's dive deeper and peek inside the "engine room". What exactly is Generative AI? How does it power these amazing capabilities? What makes these models tick? Generative AI is essentially a system combining countless learned patterns to create something entirely new. To help visualize the fundamental concept of how it works, I’ve put together another visual story. This time, it involves a rather surprising (and overflowing) box of tiny cats! As our cat-filled box illustrates, you can think of Generative AI as that brand new, super-talented cat that emerges. It can meow happily, purr with contentment, and knows all the best…  ( 5 min )
    Taking screenshot in background from Android App (Android Studio-Java)
    I’m developing a parental control app (Android 14-15, Android Studio Java) and need to take screenshots on a child’s Android smart phone(Samsung A15). However, all the common solutions I’ve found is just the MediaProjection API—have major limitations. For instance, it requires user approval every time the device reboots, and apps like YouTube can interrupt the recording process when they enter full-screen mode. Despite this, I’ve seen some parental control apps like Ever Accountable that request permission only once(Not Screen Recording-Installed Apps, but Accessibility, Device Administrator, Usage Stats and Notifications), can take screenshots silently in the background, and are not affected by interruptions from other apps. Can someone please recommend a proper, persistent solution for taking background screenshots without requiring repeated user interaction or being interrupted by other apps?  ( 3 min )

    Solitude: Not A Flaw But A Choice
    Many people who seek solitude are often misperceived because our society places such a high value on socializing and joint activities. The one who skips the group event and hides in a corner, rather than participating in conversation, often ends up being labeled as a hermit or even friendless. In fact, choosing to be alone might be a positive and self-aware choice plenty of people make. Alone does not always mean lonely. Solitude is a refuge from the external world where quietness enables reflection, feelings are able to make sense of and lasting peace is found. A person who decides to spend time alone does not want to avoid others. It is about returning to oneself. Understanding the Appeal of Solitude Everyone has a unique amount of energy and interaction they are comfortable with. Others…  ( 5 min )

    Organizing network calls in Web Apps with Concentric Call Methodology
    Table of Contents: Intro Documentation Each API gets a file Proxies and Environments Verbs live in one place Non-network data Benefits In conclusion As a UI Architect one common problem space I've noticed across teams and repos is how to organize network calls in web apps. Without a plan in place, you are likely to naively just call axios or fetch from any random component, JS file, or global store. Or you may try moving all network calls into your global stores so at least there is some consistency and it gets them out of the components. We tend to think of network calls as just a simple function that has two results (success/failure). This thought process can lead to underestimating the need for putting in the effort to organize them better. You may easily end up with a ton of network ca…  ( 11 min )

    Using elastic search to optimize text search 🔍
    Text-based searches can be slow in relational databases, especially when dealing with large datasets. This is because these databases are primarily designed for structured data and not optimized for full-text search. When performing such searches using operators like LIKE, the database often needs to examine each row individually to find matches. This row-by-row comparison is inefficient and can lead to timeouts or significant performance issues, particularly with large volumes of data. To optimize the text searches we can use Elastic search. To observe the power of elastic search, lets take an example of REST api built with express. 1. Create an express app New express app is created with 2 routes - 2. Set up mySQL and elastic search client npm i mysql2 @elastic/elasticsearch 💡 Note: Elastic search service should be running on local port 9200. Elastic search requires creation of index before we can insert data , similar to a database in mysql. For index creation checkout the full source code added at the end of the article . 3. Set up routes for REST api Route creation for path dbSearch which uses mySQL Route creation for path elasticSearch using elastic search Both the queries are similar. 4. Start up express server and test REST api Rest Api using mysql Rest Api using elastic search The search performed using elastic search is ~165% faster on average.

    Will AI Replace Your Job? Yes — Unless You Learn to Lead It
    ✅ Yes – if you don’t adapt, it will replace you. ✅ Yes – if you ignore it, you will be left behind. But if you embrace it, AI becomes a powerful ally — not a threat. “Is AI going to replace developers?” And the answer is: Not the good ones. AI can assist with small tasks. It can generate snippets. It can even help brainstorm ideas. But when it comes to: Rolling out a full application Designing a secure, scalable architecture Setting up complex infrastructure or clusters That still requires human expertise. That still requires you. We need architects — People who understand logic, structure, and strategy. AI is only as smart as the instructions it gets. So the question isn’t whether AI is a threat. It’s whether you’ll lead with it – or get left behind by it.  ( 3 min )

    Why Caching Matters More Than You Think (A Real-World Example)
    We all love to build things that “just work.” But sometimes, the very things that seem perfect on the surface can silently rack up technical debt, or worse, financial cost. Let’s talk about caching. Sometime last year, I implemented a payment integration flow: Generate a token Authorize the request Create a payment link It was seamless. This setup successfully handled hundreds of thousands of deposits. No errors. No downtime. Everything looked rock solid. Until about 6 months later. Our payment gateway provider reached out: "We’re seeing a spike in token generation. It’s burning through our resources." My first reaction: Wait, what? We followed the docs and generated a new token before every payment. Nothing seemed wrong. But here’s what we missed: each token had a 20-minute lifespan. Yet,…  ( 4 min )

    DIY Ticketing System with Google Apps Script for Handling Inquiries

Sometimes our IT-related team handled the issues, and other times we had to forward them to the appropriate department. Of course, that meant forwarding the emails. I hadn’t seen dozens of endless “Re:Re:Re:” threads in a while. It felt like time-traveling back to the 2000s when I first entered the workforce.

    🚀Migrating from Heroku to AWS with Terraform — A Real-World Guide
    As businesses grow, platforms like Heroku often become limiting. You start to feel the need for more control over networking, infrastructure, security, and scalability. That’s exactly where AWS comes in — but transitioning from a PaaS like Heroku to a powerful IaaS like AWS can feel overwhelming. At Hybytes, we’ve helped several teams migrate from Heroku to AWS using Terraform, and in this post, I want to share a breakdown of how to approach this migration in a structured, repeatable way. Heroku is great for getting started fast. But for growing teams, it brings challenges like: High costs at scale Limited infrastructure control Vendor lock-in Basic security/compliance tools AWS provides the flexibility and scale you need — but requires good DevOps practices. We used Terraform to provision and manage infrastructure across: VPC, Subnets, Security Groups Amazon RDS (PostgreSQL) Amazon ECS/Fargate for containers SSM Parameter Store for config and secrets ALB + Route 53 for traffic routing We broke down the migration into clear stages: infrastructure setup, data migration, containerization, CI/CD pipeline, then DNS cutover. Always start with a staging environment before going live Use Terraform workspaces to manage multiple environments Set up CloudWatch and cost alerts from day one Replace Heroku Config Vars with SSM parameters securely Terraform GitHub Actions for CI/CD Docker + Amazon ECR pg_dump / pg_restore for PostgreSQL migrations Datadog for monitoring Moving from Heroku to AWS isn’t just a technical migration — it’s a shift in how your team builds and operates. With Terraform, it becomes much more manageable, auditable, and scalable. We’ve documented our full guide here: If you're planning something similar, feel free to connect.

    How to view productivity
    We maximize what we measure. Without clarity on purpose, we measure the things that make us feel good. These pleasures distract us from deriving joy from what we maximize. In short, we (I) tend to focus on the input more than impact. By understanding how to define and measure productivity for ourselves, we reset our focus. First we will define productivity, then we will understand how to use all sources of information, last we'll look at 6 lenses we can use to view our own productivity and how we can "clean the lense" to have a more clear picture. If we define productivity as "the ability to have impact," our metrics for whether we are productive are subject to the context in which we operate.

The job search process is often fragmented and inefficient. Job seekers have to juggle multiple platforms, while employers struggle to find the right candidates quickly. Communication between parties is typically slow, relying on email exchanges that can take days. I wanted to build a solution that: Centralizes the job search experience Provides immediate communication between candidates and employers Creates a seamless application tracking system Works well for both sides of the hirin…  ( 5 min )

    Blockchain Beginner guide
    Introduction Blockchain has evolved from a niche concept underpinning Bitcoin to a rich ecosystem of cryptocurrencies, smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), Web3.0, and more. At first glance, terms like Bitcoin, Ethereum, Solana, ADA, NFT, DeFi, Web3.0, Binance, MetaMask, and MEW can feel overwhelming. This article breaks down core concepts, traces key milestones, explains why Bitcoin and base chains (Layer 1) were needed, and compares major platforms (Ethereum, Solana, Polygon, XRP) as well as the latest consensus algorithms. Early Inspirations (1991–2008) 1991: Haber & Stornetta propose a tamper-evident timestamping scheme. 1998–2004: “b-money,” “bit gold,” and “Reusable Proofs of Work” lay groundwork for distributed digital cash. Bitcoin’s Genesis …  ( 5 min )
    Virtual DOM & what is its role in React?
    First, let’s understand what is DOM: DOM stands for Document Object Model. DOM is a tree-like structure that represents the HTML elements of a webpage. It’s like a blueprint for a webpage. (i) Document- It’s the file where the HTML elements are stored. (ii) Object- Each HTML element/tag is an object. (iii) Model- The model is the hierarchy/sequence of the HTML elements. A developer accesses this DOM to modify/change the structure, style, and content to update the webpage layout using a programming language like Javascript. Why Virtual DOM: Direct manipulation of real DOM is slow, inefficient and reduces performance. While direct manipulation, the browser recalculates the layout of the webpage and repaints it. So multiple or small frequent DOM changes may lead to frame drop, delayed interaction or freezing. Virtual DOM resolves these issues. What is Virtual DOM: Virtual refers to something that has the characteristics of something real but not the real thing itself. So virtual DOM resembles the actual/real DOM but is not the actual DOM itself. We can define virtual DOM like this: Virtual DOM is a lightweight, in-memory representation of the actual(real) DOM. Role of Virtual DOM in React: 1) Initial Render: When a React component renders, it creates a Virtua DOM tree that mirrors the structure of real/actual DOM. 2) State/Props change: When state or props update, React creates a new Virtual DOM tree. 3) Diffing: Now React compares this newly generated Virtual DOM with the previous Virtual DOM to identify the differences and determine the minimal set of changes needed to avoid unnecessary updates to the real DOM. 4) Reconciliation: Only the differences like updated text and added elements are applied to the actual DOM. This is called reconciliation. This way react avoids unnecessary rerenders & updates the webpage quickly & efficiently.  ( 3 min )

    ⚠️ The Silent Killers: How Ignorance and Indiscipline Can Destroy a Company from Within
    “The chains of habit are too light to be felt until they are too heavy to be broken.” In startups, we obsess over product-market fit, fundraising, frameworks, and features. But what if the rot isn’t outside — what if it starts from within? As the co-founder and CTO of a 12-year-old tech firm, let me say this bluntly: it's not the market, not the tech, not the competition — it’s me. Ignorance doesn’t always shout. Sometimes it sits quietly in the corner: Not knowing how your developer interpreted a feature. Not reviewing the pull request — just merging to “save time.” Not asking “what went wrong” when a module fails. Not tracking what wasn’t done — only what got shipped. We ignore because we trust. “it’ll work itself out.” But the truth is: every bug left untraced, every ambiguity left uncl…  ( 4 min )

    Is Time Tracking the Missing Piece in Agile Dev Teams?
    In the world of Agile, we plan sprints, run stand-ups, and continuously adapt. Yet one thing often goes under the radar: how our team spends its time. Sure, Agile emphasizes working software over comprehensive documentation, but if we're not measuring time, are we missing a critical part of the feedback loop? Let’s explore how time tracking, when done right, can be a powerful tool for Agile teams. Velocity charts, burndown graphs, and story points are great. But they don’t always answer questions like: Why did this sprint go off track? How much time do we spend in meetings vs. building features? Are we consistently underestimating certain types of tasks? These are the kinds of questions that time tracking helps answer. Let’s address the elephant in the room: developers tend to hate time tr…  ( 4 min )

    🌐 Demystifying “www” — and the Magic Behind It All
    A journey into how one man's frustration inside a particle lab created the foundation of the modern web. In 1989, deep within the sprawling scientific corridors of CERN in Geneva, Tim Berners-Lee faced a quiet but maddening challenge. Physicists were drowning in data — yet they had no shared way to access or link it. Information was locked inside incompatible systems. A document on a VAX machine couldn’t be easily opened by a UNIX terminal. Sharing findings required a combination of emails, FTP commands, and paper printouts. It was a fragmented world. Tim drafted a proposal: "Information Management: A Proposal." It introduced a radical thought — using hypertext over the internet to interconnect documents. A web... a World Wide Web. Before HTML, documents existed in a range of formats: Plai…  ( 6 min )

    Before I Got the Map, I Got It All Wrong
    I set out to calculate NDVI and visualize vegetation in Finland using satellite imagery. But before I could get anything meaningful on the screen, everything broke, and every fix taught me something new. This post is a breakdown of what I got wrong, what didn’t make sense, and how I eventually got it working. I started by downloading Sentinel-2 .tiff files from Copernicus. They looked fine, no errors, so I loaded them into QGIS. What I saw: a completely dark image. I assumed the darkness was normal because it was “raw data.” But something didn’t feel right. I deleted the files and downloaded another set, same issue. I tried different pixels, formats, even downloaded 32-bit, then 16-bit versions. Still dark. When I first loaded the raster in QGIS, the project was set to EPSG:3857 (Web Merca…  ( 5 min )
    Rediscovering React - Visualise algorithms in the browser!
    Recently, I took on a side project that’s been both a technical refresher and a creative outlet: a pathfinding visualizer built with React. The motivation was simple — I missed building things for the sake of building. Recently in my career, I’ve been more focused on svelte and flutter, and I wanted to reconnect with my react foundation. With no time pressure or stakeholder demands, I gave myself the space to explore, iterate, and have fun. The project itself is a visual tool that lets users see how different pathfinding algorithms work in real time. Think Dijkstra’s, A*, and BFS — animated and interactive. It was a great way to sharpen my JavaScript fundamentals, revisit React hooks and component design, and even brush up on algorithmic thinking. More than just a technical exercise, this project reminded me why I love software development and particularly frontend: the immediate feedback of building, breaking, and fixing — and the satisfaction of watching an idea come to life on screen.

    We Are Not Code Monkeys
    Let’s be honest. Some days it feels like all we do is pick up tickets and crank out features. And somewhere in all that motion, it’s easy to forget: We’re not just here to code. create. You’ve got ideas. You see the patterns. You know when something feels off in the codebase or the product. That voice in your head saying “There’s a better way to do this”? That’s not noise. That’s your engineering instinct kicking in. Yeah, maybe you're not in every product meeting. Maybe the roadmap isn’t something you get to shape yet. But here’s the truth: Culture doesn’t change from the top. It changes when the people doing the work start doing it differently. Start small: Ask why before you start coding. Suggest a better way. Clean up something messy. Pair up. Learn something. Share something. You don’t need permission to care. Engineers: Think about users. Think about systems. Think ahead. You don’t need to be a senior dev to think like one. Every team has someone who raises the bar. Someone who nudges the culture a little closer to better. Why not you? Care about quality, not just speed. Speak up when something doesn’t make sense. Push for smarter decisions — not just faster ones. When enough people take that attitude, the team shifts. The work gets better. builds cool stuff and gives a crap. You’re a builder. Start acting like it. Others will follow. 🗣️ Let’s hear it — what small things have you done to make your team better? Drop them in the comments. Someone else might need the spark.  ( 4 min )
    How to Build Heartbeats in Go: Let Your Goroutines Say 'Still Breathing!'
    Ever wonder how to make your Go services show signs of life… even when they’re bored out of their mind? You’re not alone.

    From Listing to Longevity: Why Most Tokens Fade After the Hype (And What We Can Actually Do About It)
    I recently came across Tyler McKnight’s post on what exchanges actually do after a token is listed. As someone who has worked in marketing — and more specifically in the blockchain/crypto space — I felt it raised some important truths, but also left room for deeper discussion. So here's my take. In the Web3 world, getting listed on a CEX is treated like the finish line. But anyone who’s spent time in this space knows it’s just the beginning — and in many ways, the most brutal phase for a project. Yes, listings create visibility. But the real challenge? Maintaining relevance once the launch buzz fades. As Tyler notes, exchanges aren’t here to babysit your metrics or fix your community gaps. They provide the rails — it’s up to projects to actually drive. From my experience, here’s where most…  ( 4 min )

    Logs, Metrics, Traces… Leaks? The Case for Auditable Observability
    You’ve got dashboards. You’ve got alerts. You’ve got logs going back six months. But can you answer this one question? “Who accessed this data, and were they supposed to?” Welcome to the next era of observability: auditable observability — where what you collect isn’t the only concern. It’s about who sees it, how it’s protected, and what trails they leave behind. And if you think your observability stack is ready, think again. Observability has evolved fast. In every SRE and DevOps team I know, there’s a rich landscape of: Prometheus for metrics ✅ Loki or Elasticsearch for logs ✅ Tempo or Jaeger for traces ✅ Grafana dashboards on top ✅ What’s missing? Access control. Audit trails. Data governance. Here’s what that looks like in real life: A junior engineer accidentally sees production logs…  ( 5 min )
    Abstraction feels sometimes it does more harm than good.
    Though I am quite far into my development career, a long cry away from when I first posted here a long time ago. I still struggle to understand new tools and fundamental concepts because the time between being told about a new tool or feature, e.g., Grafana, and the time to implement is very short. Usually, as there is an underlying assumption of knowledge from the wider team, or also people don't know much about the tool, but utilise abstraction to implement it as best as they know how. This leaves me feeling quite slow or feeling a bit stupid. Does anyone else feel this way?  ( 3 min )

    Coding Is Thinking: Why I Still Write Code by Hand
    I’ve been a software developer for many years. Long enough to see waves of innovation come and go—new frameworks, languages, paradigms, all claiming to be game changers. Some were. Many weren’t. But each one taught me something new and helped shape the way I think, solve problems, and build systems. That’s why I’ve been watching the current wave of AI tools—especially generative AI—with a mix of curiosity and caution. Do I use AI in my day-to-day work? Occasionally, yes. Tools like GitHub Copilot can speed up some parts of coding. They can help scaffold a function or remind me of a syntax detail I forgot. They’re useful in the same way autocomplete or Stack Overflow is useful: a reference, a boost, a convenience. But I don’t let these tools do the thinking for me. I prefer to keep my cogni…  ( 6 min )

    Traits in PHP – a powerful yet underused tool?
    📝 This article is an English translation of the original French version available here: https://victor-prdh.com/blog/02-traits-avec-php/ PHP does not support multiple inheritance. To work around this limitation, Traits were introduced in PHP 5.4. They allow injecting methods into several classes without using class inheritance. When misused, they can harm readability and maintainability. When mastered, they are a great tool to structure shared code. Here's an overview of use cases, best practices, and common pitfalls. In PHP, a class can only inherit from one parent class. Traits allow factoring reusable behavior into multiple different classes. trait LoggerTrait { public function log(string $message): void { echo "[LOG] $message\n"; } } class ServiceA { use LoggerTra…  ( 4 min )

    The Gamma Distance Forecasts All-Cause Death in Chronic Dialysis Individuals.
    The lowest damage values were among the predator insects (Cleridae, Trogossitidae, Cantharidae) and those feeding on fungi colonized on the wood (Mordellidae, Cerylonidae, Nitidulidae). Some other predator insects of the Tenebrionidae family (Uloma cypraea, Uloma culinaris, Menephilus cylindricus) and Elateridae family (Lacon punctatus, Ampedus sp.) exhibited relatively higher damage severity values since they had built tunnels and made holes in the stored wood material. When the environmental factors were considered, the Buprestidae family exhibited a very strong positive relationship (p  less then  0.005) with insect frequency distribution (r = 0.922), number of species (r = 0.879) and insect density (r = 0.942). https://www.selleckchem.com/products/blu9931.html Both families showed the …  ( 5 min )

    Understanding HTTP Request Headers: Classification, Behavior, and How Servers React
    Demystifying HTTP for Web Developers — Part 3 In Part 2 of this series, we dissected the structure of an HTTP request — from the request line to headers and message body. We saw how a minimal request could be valid, but real-world HTTP traffic rarely resembles those minimal forms. In practice, requests are filled with headers that instruct servers, inform intermediaries, and enable negotiation. Request headers are not mere accessories. They are the instruments through which clients express identity, context, preference, and security credentials. They control everything from whether a server compresses a response to whether the request is authorized. Without headers, HTTP cannot fulfill its role as a stateless, flexible, and interoperable protocol. In this article, we shift our focus fro…  ( 7 min )

    Import Maps: Why Nobody Talks About Them (But Maybe Should)
    You know what sucks? Bundling. Install react → ends up in node_modules/, goes through Vite/Rollup/webpack, gets transpiled, hashed, minified… just so you can write: import React from 'react'; But what if you didn’t need a bundler at all? Import Maps are a native browser feature (yep, no polyfill needed in modern Chromium) that let you map bare module specifiers to real URLs — directly in the browser. Here’s the magic: { "imports": { "react": "https://esm.sh/react@18", "react-dom": "https://esm.sh/react-dom@18" } } Now, in your , you can write: import React from "react"; And the browser knows where to get it, no bundler, no build step, no CDN script tags. No build step: Instant dev workflow No node_modules/: Zero install, zero bloat Works with CDNs like Skypack, ESM.sh, JSPM Great for micro frontends, prototypes, and fast loading islands Not supported in all browsers yet → Mostly just Chromium for now. Firefox is dragging. Safari? Radio silence. (You can polyfill it, but it kills the whole “zero tooling” idea.) Tooling momentum is too big → Everyone already uses Vite, webpack, etc. Import Maps don’t fit the current “npm install + dev server” mindset. No ecosystem support → Most tutorials, libraries, and docs assume you're bundling. Period. Import Maps shine when you want: No build tools at all To prototype quickly To ship something truly small To combine multiple micro-apps without a monolith They’re especially useful with: Web components Vanilla JS apps Islands architecture setups (Astro, Marko, etc.) JAMstack sites that want dynamic bits without bundling Import Maps don’t want to replace your build system. They’re just saying: "Hey... you might not need one." They're not mainstream (yet), but they offer a glimpse at a simpler frontend world — one where browsers do more and you ship less. Worth keeping an eye on.  ( 4 min )
    Microservices simply
    Microservices have been a topic that has been revolving in my mind for some time. I wanted to find out what the big deal is behind all of that. Microservices is an architecture where we create a system with loosely coupled services each that can be scaled in isolation. Microservices talk to each other via protocols like HTTP, gRPC etc. Each MS can be individually deployed and has its own database. So total isolation. But it comes with the overhead of managing each one too. There is also the problem that now databases can't have foreign key relationships. It is a good way to show separation of concerns as the microservices are totally isolated. The key component is the API gateway which acts as a proxy to the services. Everything hits the gateway and is then routed. Last but not the least, it is not meant for small projects. It is best for large teams with each micro-team working on a micro-service. So I went out to make it happen and get over with the fuss once and for all. Like always I went ahead with my most favourite thing in the world - a todo application. Here is the architecture User Domain - a user micro-service that creates and gets users. Todo Domain - a todo micro-service that adds and fetches todo items for the users API Gateway - a gateway that acts as a proxy and routes requests.

    Basic API Security Testing Checklist for Developers and Pentesters
    APIs are the backbone of modern applications, but they are also frequent targets for attackers. Whether you're a developer securing your own API or a red teamer probing for weaknesses, it's important to understand the core areas where APIs can be vulnerable. Below is a basic but powerful checklist covering essential security testing practices — from authentication issues to privilege escalation, credential leaks, and pivoting. 1. Authentication & Authorization Hardcoded Credentials Check for credentials hardcoded in client-side code, headers, request bodies, or exposed through misconfigured API documentation. Try common combinations like admin:admin or test:test. Many APIs still ship with default credentials that are never changed. Some endpoints might not require authenticat…  ( 5 min )

    “आरंभी शूर”: The Brutal Truth About Me
    I’ve started more things than I’ve finished. There’s a Marathi phrase that haunts me: “आरंभी शूर” — brave only at the beginning. That’s been me. Every few weeks, I would ignite a new initiative. And then… The energy would dip. I wasn't lazy. I was just undisciplined. start. Why I Started Strong Because beginnings are easy. Starting made me feel in control. So I jumped to the next thing, chasing clarity where none existed. What It Cost Me A backlog of 80% complete initiatives Loss of credibility with my own team Technical debt disguised as momentum Incomplete loops in validation, delivery, and feedback And most painfully — a reputation for “getting things started” But never enough for “getting things done.” Code, Culture, and Closure I prided myself on innovation. But what I needed was consistency. closure. Code went unchecked. This isn’t just a workflow issue. me issue. What I’m Doing Now I’ve decided to break this cycle. No new initiatives until old ones are closed. No task is “done” until validated, tested, and documented. No PR is merged unless reviewed — fully, fearlessly.

    Understanding API Loading Delays: Common Causes
    When an API is loading slowly, there could be multiple reasons behind it. Here’s a breakdown of common causes and what they mean: ⚙️ 1. Client-Side Issues 🐢 Slow internet connection (e.g., poor mobile data or Wi-Fi) 🕰️ Blocking synchronous code on the frontend, like large loops or animations that freeze UI 📦 Rendering too much data at once (e.g., a huge React table without pagination or virtualization) ❌ No loading indicators, which can make users feel the app is slower even if it isn’t 🌐 2. Network Issues High latency due to physical distance between client and server Network congestion or packet loss slowing requests Firewall or proxy issues blocking or delaying requests 🖥️ 3. Server-Side Issues Server overloaded and can’t handle many concurrent requests Synchronous/blocking operations in business logic causing delays Database slow queries or locks slowing down responses Not using asynchronous processing where appropriate 📈 4. Design and Architectural Factors API not designed for scalability or optimized for quick responses Missing or inefficient caching mechanisms Too many unnecessary data payloads increasing transfer size 📡 5. External Factors Third-party services or APIs called inside your API causing delays Geographic location mismatch causing longer data travel times If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )
    Decoding Image Segmentation: From Basic Pixels to Panoptic Perfection
    In the fascinating world of computer vision, segmentation isn't just about cutting images into pieces—it's about giving meaning and structure to every single pixel. But not all segmentation is created equal. There are four primary types, each serving a distinct purpose and offering increasing levels of detail and understanding. At its most fundamental level, Image Segmentation divides an image into logical groups of pixels based on criteria like color, texture, or intensity. Think of it as drawing boundaries around areas with shared characteristics. Groups pixels into regions (e.g., "this blob is a tree"). Outputs contours (outlines) or masks (filled areas). Uses pseudo-coloring to differentiate segments visually. Isolate distinct pixel groupings without assigning semantic meaning. Buildin…  ( 4 min )

    The Invisible Gap That Cost Us 12 Years: Lessons in Software Quality from the Trenches
    “You don’t ship code. You ship decisions. And we made too many of them blindly.” For over a decade, at DoozieSoft, we built. We delivered. We grew. But amidst the commits and deployments, one critical piece kept slipping through the cracks — Validation. Not validation of forms or user inputs — we had those. But the real validation loop: What was tasked vs. what the developer understood What was built vs. what the client wanted What was tested vs. what was shipped What was reviewed vs. what was merged This silent fracture led to a systemic dysfunction: Code was written without clarity, merged without critique, and shipped without accountability. The Broken Loop Tasks were often communicated ad hoc, over calls, or in fragments. Developers made assumptions. Testers raised flags. Fixes…  ( 4 min )

    Mastering Exception Handling in PHP 8: A Deep Dive into try-catch Enhancements
    Exception handling in PHP has evolved significantly with PHP 8, giving developers powerful tools to manage errors more efficiently. If you're working with PHP, understanding how try-catch blocks work and how to handle exceptions correctly is essential for writing robust and maintainable code. Exception handling is the process of managing errors or unexpected behavior in a program. In PHP, this is typically done using the try-catch construct. The try block contains code that might throw an exception, while the catch block handles the exception. With the latest updates in PHP 8, this process has become more streamlined and developer-friendly. One of the key improvements in PHP 8 is its support for multi-catch blocks. This means you can now catch multiple exception types in a single catch cla…  ( 4 min )

    Step-by-Step on how to Link SSH to GitHub from Your Server
    When you use SSH to clone a GitHub repository on your server, you’re authenticating the server to GitHub using an SSH key. Here's how it's linked: You generate an SSH key pair on your server. The private key stays on the server. The public key is copied to GitHub. When you run a command like: git clone git@github.com:your-username/your-repo.git GitHub checks: “Does this public key match one of the authorized SSH keys on this GitHub account?” If yes, access is granted, and cloning happens without asking for a username/password. Contabo server, generate an SSH key: ssh-keygen -t rsa -b 4096 -C "your-email@example.com" Press Enter for all prompts to accept defaults. cat ~/.ssh/id_rsa.pub Copy the output (it begins with ssh-rsa...). Settings → SSH and GPG keys → New SSH key Title: Contabo server Paste the key ssh -T git@github.com If successful, it will say: Hi your-username! You've successfully authenticated... git clone git@github.com:your-username/your-django-repo.git tunaresq_be No username/password will be required — it just works 🎉.  ( 3 min )

    Declare an array in TypeScript
    Article published on my blog here : https://alsohelp.com/blog/typescript-declare-array How to declare an array in TypeScript the right way. A small recap, mostly note to self. First, this is how you declare an array in JS : const fruits = ['apple', 'orange', 'banana']; Remember that TS generates JS, so you always end up with the above. In TS, it will look like this: const fruits: string[] = ['apple', 'orange', 'banana']; You are telling TS "I'm declaring an array of string". In TS, you always declare an array of something. an Array of string, an Array of number, an Array of MyType, and so on. There is no "array of nothing" in TS. ❌ const fruits: [] = [] // wrong! you are declaring an empty array ❌ const fruits = [1, 2, 3] // wrong! you are declaring an "array of any", like in JS ❌ const fruits: any[] = [1, 2, 3] // wrong! you are using any, which is almost forbidden in TS An array in TS is always an "array of something". I think it's the only gotcha to remember. Best, David  ( 3 min )

    Ускоряем Elixir: интеграция с нативным кодом (NIF, Ports и др.)
    ⚠️ Важно: Перед внедрением новых языков в проект сначала убедитесь, что код на Elixir был максимально оптимизирован. В большинстве случаев грамотная оптимизация текущего кода значительно улучшает производительность приложения и иногда даёт лучшие результаты, нежели добавление другого языка программирования. Elixir и Erlang — отличные языки для разработки масштабируемых и отказоустойчивых систем. Но иногда нужно выжать максимум производительности или использовать библиотеку, доступную лишь на другом языке. Если вы попали именно в такую ситуацию или просто хотите узнать, как совместить два ваших любимых языка программирования, эта статья для вас! 🔍 Когда нужна интеграция с нативным кодом Прежде чем углубляться в технические детали, важно понять, когда стоит рассматривать…  ( 12 min )
    Coding with Others
    Pair programming is a worthwhile activity that I do in my apprenticeship. I practice pair programming during my in-class workshops. I also participate in pair programming with my partner for our capstone project. This activity has given me lots of practice working with someone to solve a problem. I do believe I learned valuable lessons about programming and teamwork because of this. It may seem obvious, but pair programming really shows the importance of being able to communicate effectively. Conveying your ideas in an understandable and meaningful way is important to minimize confusion and ensure everyone is on the same page. Another lesson that I learned is that it is beneficial to ask questions and ask for assistance if needed. Every time I needed help, my coding partners were happily willing to give an answer or clarification as needed. I also learned that coding together is an excellent way to improve and share knowledge with peers. Practicing pair programming is a superb way to give early-career software engineers some hands-on experience in that environment. Since it is common to code in a team professionally, pair programming practice provides a terrific glimpse into how to maneuver in that environment. Coding with others allows one to develop not only their hard skills but also improve soft skills as well. Going forward, I think the best way to get more out of these experiences would be to expose myself to more pair programming. Additionally, going into these sessions with a goal in mind is a fantastic idea. For example, one day complete an exercise with a focus on working on your communication and asking questions. Then, on another day, challenge yourself by trying a different language. Another way to get the most out of pair programming is practicing being the driver and the navigator.  ( 3 min )

    Python has map() and filter()? How come no one told me?
    As a new python developer, fresh off my first major project, I'm pretty excited about the language. So excited that I can't resist learning more and more by watching content from seasoned developers. Recently, I came across a video titled "map() and filter() in Python!" This piqued my interest because I hadn't been taught these inbuilt functions; I had only ever been taught how to approximate these using list comprehensions. I thought to myself "Surely an inbuilt function for such a thing MUST be better than typing out an entire comprehension!" After watching the video and learning the functions, I still felt unclear on whether or not these functions would be superior to list comprehensions. So I decided to put them to the test, head to head. Right off the bat, it's important to not that t…  ( 5 min )
    Stop Hesitating, Just Use React Or Any Modern Framework
    Why does it matter? The web today is no longer just a collection of simple static pages. It’s where businesses run, communities connect, and complex interactions happen.

But building an app with: Complex interactive UI Multi-dimensional user state management Real-time data updates Reusable, maintainable components And proper accessibility for all users requires way more. Frameworks like React are powerful tools that help you handle all that complexity easily instead of wrestling with tons of manual DOM manipulation.

    Beyond IT School: How I Spent 4 Months Enhancing My Portfolio
    Hey everyone! mine – digging deeper with the tools and tackling stuff beyond what they taught us. Here’s a quick look at what I’ve been up to. I started with a template, but pretty fast, I was tearing apart and rebuilding most of it. Seriously, not just tweaking colors. I had to dig deep, wrestle with some tricky JavaScript, and basically remake huge chunks. Honestly, sometimes I figured it’d be easier to just build from scratch! Anyway, Chrome DevTools was my best friend through all this. Constantly in the 'Elements' panel, and using 'Computed' and 'Styles' to test things live. Really helped me get why stuff worked (or didn't) and how to fix it. A smooth, fast site was a big deal for me: Better Images: Switched some images to compressed PNGs and added lazy loading to speed things up. C…  ( 4 min )
    DevLog 20250520: Search Engine Architecture
    Overview For an internal database, we needed to implement some sort of text-based search capabilities to help users locate documents. One goal was to be lightweight, hassle-free, easy to set up, expand, and maintain—and ideally, to set it up once and forget about it. It's okay if it costs a bit of computing power, but agility, quick iterations, usability, and robustness are of top concern. It's surprising how much we can do without a server. Most serverless or static webpage hosts are happy to serve anything from a few MB to a few GB for free, likely even distributed across the globe. For any particular individual, if the search experience is truly customized to their needs, then not much resource is needed to deliver a satisfying experience. Let's illustrate this with an example.

    How to Turn Your Artwork into NFTs and Sell It Like a Pro (Even If You’re Not a Techie)
    Art isn’t just on canvases anymore—it's living on the blockchain. Whether you're a digital Picasso or just have killer album art, converting your work into NFTs could unlock a world of passive income, global collectors, and Web3 magic. Here’s how to do it, step by step. Your blockchain determines everything—fees, community, and speed. Ethereum: Expensive, prestigious, whale-heavy Polygon: Eco-friendly, gasless minting, great for new artists Solana: Fast, low cost, preferred by gaming and indie artists Tezos: Artist-focused, sustainable, low-fee Pick the one that suits your audience and goals. Your art file should be high-quality and in digital format: Images: JPG, PNG, GIF Videos: MP4 Audio: MP3 3D: GLB/GLTF Pro tip: Add utility like unlockable content or physical art delivery for extra value. You’ll need this to interact with marketplaces and sign transactions. MetaMask (Ethereum/Polygon) Phantom (Solana) Kukai/Temple (Tezos) Save your seed phrase like it’s your birth certificate + wallet + ATM pin. This is where the NFT magic happens. "Minting" is how your artwork becomes an NFT on the blockchain. Connect your wallet Upload your artwork Fill in the metadata (title, description, royalties, etc.) Pay the gas fee if required Click mint! Boom. You just immortalized your art. Once minted, you can either: Sell at a fixed price Run an auction Hold it as a reserve piece Then get loud: Promote on X/Twitter Join Discord art communities Collaborate with NFT influencers You don’t need to be a dev or a crypto bro to get started. All you need is great art, a wallet, and a bit of Web3 curiosity. Your next masterpiece could be someone’s next prized collectible.  ( 4 min )

    Sam Altman's World raises $135M from Andreessen, Bain, to expand network
    World, OpenAI CEO Sam Altman’s digital identification project, raised $135 million from venture capital firms Andreessen Horowitz and Bain Capital Crypto, the company said in an announcement. The capital will be used to expand World's network of iris-scanning orbs and infrastructure in the United States, where the company said in April it would operate in six cities, and increase coverage around the globe, according to the announcement. More than 12.5 million individuals in over 160 jurisdictions have been issued a World ID, the company said. The project, which collects biometric data from individuals to establish "proof of personhood," faces regulatory headwinds and bans in several countries. Critics of the project say that offering financial incentives for biometric data violates informe…
    Jury convicts ex-SafeMoon CEO on all charges
    A New York jury found Braden John Karony, the former CEO of cryptocurrency company SafeMoon, guilty of three felony charges after less than a day of deliberation. According to May 21 reporting from the courtroom, in the US District Court for the Eastern District of New York, a jury convicted Karony of conspiracy to defraud the United States, money laundering, and wire fraud. Prosecutors and defense lawyers presented their cases over the roughly two-week trial that kicked off with jury selection on May 5. Karony, former chief technology officer, Thomas Smith, and the platform’s creator, Kyle Nagy, were charged in 2023 for having allegedly “diverted and misappropriated millions of dollars’ worth” of SafeMoon’s SFM token. Smith testified against Karony at trial, while Nagy reportedly fled to Russia and was at large as of May 21. The criminal trial involving a cryptocurrency company executive was seen by many as a bellwether for how Joseph Nocella, the interim US Attorney for the district, could handle cases involving digital assets and fraud. Nocella, a Donald Trump appointee, took office on May 5. This is a developing story, and further information will be added as it becomes available.

    Bitcoin hits new highs in the absence of ‘unhealthy’ leverage use — Will the rally continue?
    Key takeaways: Spot Bitcoin ETF inflows and low leverage suggest the BTC rally has room to grow. US Federal Reserve liquidity and weak bond sales support a Bitcoin push beyond $110,000. Bitcoin (BTC) was unable to sustain its bullish momentum after reaching a new all-time high of $109,827 on May 21, which led traders to question whether derivatives markets mainly drove the rally.

    Interest groups, lawmakers to protest Trump's memecoin dinner
    Democratic leaning organizations and members of Congress have announced plans to protest what they describe as the sale of access to the office of the US president, in reference to Donald Trump’s memecoin dinner on May 22. The event’s attendees are said to have collectively spent over $100 million for the chance to meet with the US president.

    Texas House passes strategic Bitcoin reserve bill
    The Texas House of Representatives has passed the third reading of SB 21, a bill that seeks to establish a strategic Bitcoin reserve in the state. The bill passed in a 101-42 vote and will now go to Texas Governor Greg Abbott to either sign into law or veto.

    Crypto's real momentum isn't in the charts; it's in developer activity
    Opinion by: Markus Levin, co-founder of XYO The crypto community often experiences periods of heightened anxiety. Market downturns are often triggered by counterproductive sentiment-driven events rather than by fundamental issues, creating a significant disconnect between price behavior and the actual progress being made within the industry by the companies within it. What often goes unnoticed is how much real development happens during these downturns. While market movements capture most of the attention, teams are building faster and more deliberately behind the scenes than ever. The focus shifts away from price speculation and toward real execution. Growth happens during downturns. It's a necessary phase for projects that thrive in a volatile industry. They re-focus attention on refinin…
    How to handle crypto trading gains and losses on your balance sheet
    Key takeaways Properly accounting for crypto assets on your balance sheet is essential for accurate tax reporting and financial transparency. Crypto trading activities should be recorded like stock trading, at fair market value on the day of purchase. In some countries, like the US, crypto losses can offset gains, so keeping track of gains and losses is important for reducing taxable income. Whether you’re an individual investor or a business, treating cryptocurrencies as assets and documenting them ensures compliance with tax laws and minimizes the risk of errors. Let’s be real, it’s easy to lose sight of what you’ve actually gained or lost, especially when it comes to crypto and its market volatility and frequent trading activities.  And when it comes to accounting, especially in countr…

    Yield-bearing stablecoins have soared to $11 billion in circulation, representing 4.5% of the total stablecoin market, a steep climb from just $1.5 billion and a 1% market share at the start of 2024.

    SEC’s Peirce says NFT royalties do not make tokens securities
    United States Securities and Exchange Commission (SEC) Commissioner Hester Peirce said many non-fungible tokens (NFTs), including those with mechanisms to pay creator royalties, likely fall outside the purview of federal securities laws. In a recent speech, Peirce said NFTs that allow artists to earn resale revenue do not automatically qualify as securities. Unlike stocks, NFTs are programmable assets that distribute proceeds to developers or artists. The SEC official said that mirrors how streaming platforms compensate musicians and filmmakers.  “Just as streaming platforms pay royalties to the creator of a song or video each time a user plays it, an NFT can enable artists to benefit from the appreciation in the value of their work after its initial sale,” Peirce said.  Peirce added that …

    Why crypto transfers can fail and what you must check before sending
    Why crypto transfers can fail and what you must check before sending Crypto transfers fail more often than most people realize, but user attentiveness can stop most losses. What’s often marketed as a seamless, borderless system can become frustrating when transfers fail, with no customer service hotline to call and no easy recourse to reverse mistakes.

    SEC delays decision on Ether staking and XRP ETFs, as analysts expected
    The US Securities and Exchange Commission has delayed its decision on Bitwise’s application to add staking to its Ether exchange-traded fund and on Grayscale’s XRP ETF bid, which analysts had expected.

    SEC charges Unicoin and executives for alleged $100 million fraud
    The US Securities and Exchange Commission has charged crypto platform Unicoin and three of its executives, alleging they made false and misleading statements about its crypto assets that raised $100 million from investors. The SEC said on May 20 that it charged Unicoin CEO Alex Konanykhin, board member Silvina Moschini, and former investment chief Alex Dominguez with misleading investors about certificates that conveyed rights to receive Unicoin tokens and stock. Mark Cave, associate director in the SEC’s Division of Enforcement, claimed the trio “exploited thousands of investors with fictitious promises that its tokens, when issued, would be backed by real-world assets including an international portfolio of valuable real estate holdings.”  Related: SEC crypto task force to release first report 'in the next few months' “The real estate assets were worth a mere fraction of what the company claimed, and the majority of the company’s sales of rights certificates were illusory,” Cave added.

    Apple Developer Relations
    Apple's Worldwide Developer Conference is just weeks away, but I'm sensing a lot of apathy in the community. The company's relationship with third-party developers is at a low point. We all know that Tim Cook and his senior people will stand up at WWDC and say how much they value their developers and boast about how much money they've paid out to them. Being so enthusiastic about the money is very strange - it's like a rent collector bragging about how much money he has given to the landlord when all he's doing is collecting the rent and taking his cut. And it's difficult to take Apple's apparent enthusiasm for their developers seriously given their behavior over the rest of the year. Trust is a hard thing to gain. Apple used to have the developers' trust but now they've lost it. It's much…  ( 6 min )

    From EC2 to GitHub: Connecting Your Cloud Code Like a Pro
    Hey DevOps explorer! 👋 Today we're diving into Project 2 of my 7-Day DevOps Challenge, where I connect my Java web app hosted on AWS EC2 to GitHub using Git. By the end of this post, you’ll understand how to: ✅ Install Git on your EC2 instance ✅ Set up a GitHub repo ✅ Track and commit code ✅ Push code from EC2 to GitHub using a personal access token Version control is a must-have skill for any developer. Whether you're flying solo or collaborating on a team, Git and GitHub help you keep your code safe, traceable, and easy to manage. sudo dnf update -y sudo dnf install git -y Head to GitHub, create a free account (if you haven’t), and start a new repository — this is where your code will live in the cloud. 💡 A GitHub repository is like a magic folder that tracks every change in your project. git init master branch. git add . git commit -m "Initial commit" git add . stages your files, and git commit saves the snapshot. Think of it as telling Git, “Hey, these are the changes I care about.” First, copy the HTTPS URL from your GitHub repo. Then: git remote add origin https://github.com/your-username/your-repo-name.git git branch -M master git push -u origin master Oops! Git might ask for your username and password, but GitHub no longer accepts passwords. Go to GitHub → Settings → Developer Settings → Personal Access Tokens. Generate a token with repo access and copy it. Use it when Git asks for a password. 🔐 A GitHub token is a secure key that acts like a password for Git operations. I updated index.jsp, then ran: git add . git commit -m "Updated homepage" git push And just like that—my changes appeared live in the GitHub repo. Magic! Services used: EC2, Git, GitHub, VS Code Concepts learned: version control, repo setup, staging/commits, GitHub tokens This project took me around 2 hours. The trickiest part? Setting up GitHub authentication. The best part? Watching my code go live in my repo with one command. This is just the beginning. Stay tuned for Project 3 tomorrow—CI/CD, here we come! 💥  ( 4 min )

    The Serverless Dream Is Dead
    For years, serverless was sold as the future. No servers to manage. Just write a function, deploy it, and let the platform scale it for you. AWS Lambda kicked it off, and then everyone followed: Vercel, Cloudflare Workers, Deno Deploy. But the dream is falling apart. Last week, Deno quietly announced that they're scaling back Deploy's global footprint from 35 regions to just 6. And performance actually improved. It's not a sign that serverless is dead, but it is a clear signal: trying to stretch Functions-as-a-Service (FaaS) into a general purpose app platform hasn't worked. The original pitch was simple. Write a small function. Don't worry about infrastructure. It scales when you need it. You only pay when it runs. And it works well for the right use cases: Webhooks Scheduled tasks Backgr…  ( 6 min )

    The Rise of DNA Computing — Biology’s Answer to Silicon
    Alireza Minagar, MD, MBA, MS (Bioinformatics) The most iconic breakthrough came in 1994 when Leonard Adleman used DNA to solve a variation of the Hamiltonian path problem — essentially using a wet lab to tackle a mathematical graph problem. The outcome wasn’t just symbolic; it showed that biology could compute. ⚙️ How Does It Work? Strands of synthetic DNA to represent information. Hybridization (binding of complementary DNA strands) to encode logic. Enzymes and PCR to manipulate, amplify, and “read” molecular data. For example, each possible solution to a problem can be encoded as a DNA strand. Enzymatic reactions are then used to eliminate invalid strands, leaving only the correct solution. 🚀 Applications: Why It Matters Massive Parallelism: Billions of molecules can react simultaneously. Storage Density: A single gram of DNA can store over 200 petabytes of data. Energy Efficiency: Unlike traditional chips, DNA reactions don't generate heat or require electrical power. Biological Integration: DNA computing can be embedded directly in living systems for medical diagnostics or drug delivery. 🧪 Real-World Use Cases Encrypted bio-storage: Encoding and decoding messages inside synthetic DNA. Pathway modeling: Simulating metabolic or neurological pathways using biological logic circuits. 🤖 DNA Computing Meets AI While we're still far from such a future, foundational work in molecular classifiers, DNA robots, and synthetic biology is pushing boundaries faster than many realize. 📌 Final Thoughts As someone who works at the crossroads of medicine, computing, and biology, I believe that DNA computing represents a philosophical shift: from commanding machines to collaborating with biology. 👨‍⚕️ About the Author Alireza Minagar, MD, MBA, MS, is a neurologist, software engineer, and bioinformatician exploring the convergence of AI, medicine, and molecular computing.

    Unlike Cyberpunk 2077, "Cyberpunk 2" Uses Procedural Generation
    TL;DR: CD Projekt RED’s sequel to Cyberpunk 2077—internally dubbed Cyberpunk 2 or Project Orion—is shaking up its world‐building by embracing procedural generation. A recent Boston‐based job posting for a Lead PCG/Tools Engineer confirms they’re cooking up in‐house systems to spit out urban layouts, interiors, NPCs and more, rather than hand‐crafting everything like they did in Night City. Don’t freak out about rogue-lite randomness—CDPR’s big use of PCG is behind the scenes to speed up development and potentially expand the open world beyond its previous vertical city. It’s a shift from their 2019 mantra of pure manual creation, but early signs hint it’ll still deliver that signature handcrafted polish (and hopefully a far bigger playground to explore).  ( 3 min )

    Unknown Species of Bacteria Discovered in Swabs From China's Space Station
    TL;DR: Scientists swabbed China’s Tiangong space station and found a brand-new bacterium, officially dubbed Niallia tiangongensis. This hardy microbe is a close cousin of the soil-dwelling N. circulans and packs its essential chemistry into spores to survive stress. Surprisingly, it can munch on gelatin to build protective biofilms but has lost the ability to use some nutrients its relatives love. What’s especially wild is that Tiangong’s microbiome looks very different from the ISS’s, raising questions about whether these bugs evolved up there or hitched a ride in spore form. While it’s unclear if N. tiangongensis poses a health risk to astronauts, its knack for DNA repair and toxin resistance—traits shared by other space-stubborn microbes—means we really need to know how these tiny stowaways might tag along on future lunar or Martian missions.  ( 3 min )
    A new study finds that democratic countries often appear greener because they offshore pollution to less democratic nations.
    TL;DR: Democracies often look “greener” than autocracies, but Bernauer et al. (2025) argue that a big part of this is pollution offshoring—basically buying dirtier goods from abroad and counting only domestic emissions. They crunch data on 160+ countries (1990–2015), merging V-Dem scores with both domestic CO₂-equivalent emissions and outsourced greenhouse-gas footprints. The kicker: Their analysis shows that higher democracy levels correlate with more pollution offshoring, which in turn helps drive down in-country emissions. In other words, democracies may not actually be cleaner globally—just clever at exporting their carbon. The authors urge democratic governments to shift focus from purely local regulation to accounting for the full global impact of their consumption.  ( 4 min )

    Day 8: Let’s Get Greppy – Finding Text Like a Pro in RHEL 9
    Alright, command-line comrades, it’s time we talk about someone very special… Grep — the text detective that never sleeps. If you’ve ever stared at a log file wondering if the answer to your issue is hiding somewhere in 3,000 lines of gobbledygook, grep is your new best friend. So what exactly is grep? Basic Syntax: Handy Flags for Beginners: Real World Use: Mini Mission: Why It Matters Grep stands for Global Regular Expression Print, but don't let the fancy name scare you. It basically means: “Hey Linux, find this text for me, now, please and thank you.” grep "pattern" filename Let’s say you have a file called shopping.txt and it looks like this: apples Run this, and boom — it’ll spit out: -i (ignore case) -n (show line number) -r (search recursively through directories) Now it finds both “Banana” and “banana”, and shows which line they’re on. Pretty slick. Searching logs for errors: Finding a user in /etc/passwd: Create a file with different fruit names. Use grep to find your favorites. Bonus points for using -i and -n. In a real-world tech job, whether you’re a sysadmin or cloud wizard, you’ll often need to extract one crucial line from a sea of chaos. Mastering grep saves time, energy, and possibly your sanity.  ( 3 min )
    Scaling African Startups with AWS: Lessons from Building KaziHub
    Scaling African Startups with AWS: Lessons from Building KaziHub Building a startup in Nigeria isn’t easy — slow internet, limited capital, and little support. But AWS changed the game for me. With it, I launched KaziHub, a job platform for African developers, and scaled it without owning a single server. Here's how AWS helped me do it — and how it can help you too. After a local tech conference, our traffic spiked overnight. Without AWS Auto Scaling, we would’ve crashed. Instead, the system scaled up instantly — no downtime, no stress. You don’t need a DevOps team — just good defaults and Auto Scaling. We launched KaziHub on a tight budget using AWS’s pay-as-you-go model and credits from AWS Activate. That meant we spent money on dev work, not hardware. If you’re early-stage, AWS Activate is basically free money. KaziHub runs on: S3 for storage Amplify for hosting DynamoDB for our database Lambda for backend logic We built fast — no giant engineering team needed. Even with patchy internet, users from Kenya to Ghana access KaziHub fast thanks to AWS’s global data centers. You don’t need to rent a local server anymore — AWS brings the cloud to you. With AWS handling encryption, compliance, and infrastructure security, we focused on building. That’s crucial when user trust is everything — especially in regions where fraud is a concern. We shipped new features in days using Lambda and are now experimenting with SageMaker to match devs to jobs using AI. AWS lets you prototype like a pro, even without fancy hardware. AWS’s startup events in Nigeria connected me to mentors and other founders. These networks helped guide both product and strategy. For African founders, AWS isn’t just a cloud provider — it’s a launchpad. It helped me go from idea to impact with limited funding, and now I teach cloud tools to other devs in my community. Explore AWS for Startups, apply for credits, and start small. You don’t need to over-engineer — just start. If I can build KaziHub in Nigeria, so can you.  ( 4 min )
    LLM-Powered Code Reviews: Beyond Static Analysis Tools
    In the world of software engineering, code review is our safety net, our second pair of eyes. But even the most experienced engineers can miss subtle bugs, design inconsistencies, or documentation gaps. For years, we’ve leaned on static analysis tools like SonarQube, ESLint, and CodeClimate to spot the low-hanging fruit. These tools are great for enforcing rules — “Don’t leave unused variables!” or “Mind your cyclomatic complexity!” — but they don’t really understand your code. Enter Large Language Models (LLMs). These AI systems — like GPT-4, Claude, or GitHub Copilot — are turning code review into a conversation rather than a checklist. Let’s dive into why this shift matters and what it actually looks like in practice. Think of static analysis tools as grammar checkers for your code. The…  ( 5 min )

    10 Practical Lessons Every Laravel Developer Should Know
    Throughout my journey with Laravel, I’ve learned a lot of lessons that helped me improve the way I work and write code. Here are 10 key takeaways that made a real difference for me: If you're using Blade, make sure to add required to your HTML fields. If a user submits an empty required field, it shouldn't even reach the server. Save your server from handling unnecessary requests. Always validate incoming data. Avoid using request()->all(), especially if you're using guarded in your model—it could allow unexpected data to slip through. resource or apiResource routes This helps keep your routes organized and prevents your route files from becoming bloated and hard to manage. Don't put logic inside your Resource files. It can cause N+1 problems, especially when returning collections. It also makes your code easier for others to understand. Always use pagination for large datasets. Avoid N+1 problems by eager loading any relationships you know you'll use. Laravel 12 introduced automatic eager loading, but it's still good practice to manage it explicitly when needed. Laravel Logs and tools like Laravel Telescope are great for debugging and monitoring. Just make sure to secure Telescope if you’re using it in production. Regularly delete old logs and unused files. For example, when users update profile images, delete the old one. This helps you save disk space in the long run. Use Guards, Policies, or Gates to protect your data. Never assume users should have access just because they’re logged in. Don’t let a few users flood your system with requests. Throttling is your first line of defense against DDoS attacks. Use cache for data that’s accessed frequently and doesn’t change often. It makes a big difference in performance. Final Thought: You're building for all kinds of users، always be prepared for the worst-case scenario.  ( 4 min )

    Memory Optimization in Java – Or, How to Stop Leaking Your Sanity
    Let's start with the obvious, Java is great. It’s got a garbage collector, it keeps your hands mostly clean of manual memory management, and it’ll let you write code that just works. Until it doesn’t... Until that sweet little app of yours starts slowing down like it’s stuck in mud and your grafana memory usage chart looks like it’s climbing Everest with no plans to come back. So yes... Java handles memory for you. But if you don’t understand what it’s doing behind the scenes, it’s only a matter of time before your app becomes jabba the hutt. Let’s talk about how not to let that happen. Java's garbage collector is fantastic. It takes care of unused objects so you don’t have to manually free() them like in C. But here’s the catch - the garbage collector only collects what it knows is garba…  ( 5 min )

    Fixing Vite HMR Issues in React by Splitting Your Auth Context
    Have you ever updated a file in your React + Vite project only to see full page reloads instead of fast refresh? 😩 That happened to me when I built an authentication context and exported both the provider and a custom hook (useAuth) from the same .tsx file. Turns out, that’s a no-go if you want smooth Hot Module Reloading (HMR) with Vite. Here’s what was happening and how a small refactor completely fixed it. I had a single AuthContext.tsx file that looked something like this: import { createContext, useContext, useState, useEffect, ReactNode, } from "react"; import authApi from "@/api/auth-api"; import { User } from "@/types/users"; import { AuthContextType, AuthResponse } from "@/types/auth"; const AuthContext = createContext(undefined); export fu…  ( 4 min )

    219/365 | ¥10M Job Challenge - Process for taking over a project
    Process for taking over and maintaining a project: Log in to the application server by VPN or SSH in order to understand where the project files are stored and how the deployment process works. Typically, we'll start with the HTTP server and service-related files. Log in to the database to ensure we can connect properly. Ideally, take this opportunity to dump and back up the database schema as an SQL file. Even if the project originally followed a Code First approach with migration files, it's very common for projects to shift toward a DB First setup over time, especially after being handed off between multiple developers. Not having a complete DB schema can often lead to major issues. Check how the connection strings and environment variables are applied, then run the project locally for testing. If there are too many third-party services making it hard to run locally, writing mock services could take a lot of time. In that case, the best approach is to see if we can run the project locally while connecting to the actual staging/production database for testing. (But make sure to check for background services or scheduled jobs that could cause concurrency issues.) I'll add more if anything else comes to mind. In many cases, taking over a project can be chaotic and unstructured—blindly following AI suggestions without critical thinking can easily lead to disaster.  ( 3 min )
    📝Today Blog: Creating a Product Card Using HTML and CSS Properties
    📝Today I learned how to create a product card using HTML and CSS properties. Product cards are an essential UI component in modern web design. They provide a concise, interactive way to display product details, such as images, titles, prices, and call-to-action buttons. This article demonstrates how to build a responsive and visually appealing product card using HTML and CSS, leveraging flex/grid layouts, transitions, pseudo-classes, hover effects, and relative units like rem. HTML Structure The HTML provides a semantic structure for the card. HTML structure separates visual elements clearly and provides flexibility for styling. CSS Styling To style the card effectively, we’ll use CSS Flexbox, Grid, and modern features to create a responsive and dynamic experience. Key Features Explained …  ( 4 min )
    The Danger of Overusing "is" Instead of "==" in Python
    If you've been working with Python for a while, you've probably used both is and == in your code. They look similar, they even read similarly. But underneath the hood, they do very different things. And using is when you meant to use == can lead to subtle, nasty bugs that are incredibly hard to track down. is and ==? == checks if two values are equal. is checks if two variables point to the same object in memory. Here’s a simple way to remember it: 👉 == → “Do these things look the same?” 👉 is → “Are these things literally the same object?” A Quick Example a = [1, 2, 3] b = [1, 2, 3] print(a == b) # True: the contents are the same print(a is b) # False: different objects in memory Even though a and b contain the same list values, they’re not the same object. Python created two sep…  ( 5 min )
    Understanding Loops in JavaScript
    Loops are a fundamental programming concept used to execute a block of code repeatedly under certain conditions. In JavaScript, loops are especially useful when working with arrays, objects, and repetitive tasks such as data processing or UI rendering. This article explores the different types of loops available in JavaScript, how to use them, and when each is most appropriate. Consider a scenario where you need to print numbers from 1 to 100. Without loops, you would have to write 100 console.log() statements. With loops, this task becomes simple and efficient: for (let i = 1; i <= 100; i++) { console.log(i); } Loops help reduce code redundancy, improve maintainability, and handle dynamic data structures efficiently. JavaScript provides several types of loops, each with its own syntax …  ( 5 min )
    ✨ 17 React Hooks That Power 90% of Modern Components
    New to React? If yes, you’ve probably wondered what hooks you really need—or worse, you’ve been copying the same logic over and over without realizing it. This post covers all the React hooks you’ll likely need in your project. Let’s dive in 🎉. 📚 Download my FREE 101 React Tips And Tricks Book for a head start. 1. useState This hook is unavoidable. Whenever you need dynamic state that persists across re-renders, this is the one. const [count, setCount] = useState(0); Once your state becomes complex (e.g. multiple correlated fields), useReducer becomes your friend. It also pairs really well with useContext, letting you update state with simple dispatch calls. const reducer = (state, action) => { switch (action.type) { case "addTodo": return { todos: [...state.…  ( 6 min )

    Navigating Virtual Frontiers
    Just a short while ago, virtual worlds felt rigid and choreographed. Avatars stood as lifeless mannequins, and virtual characters performed limited, predictable roles. Today, a new breath animates these digital landscapes, thanks to the nuanced orchestration of artificial intelligence. Imagine entering a virtual café—noticing your friend's subtle grin or the warmth behind their eyes, replicated faithfully in the avatars gathering around you. Platforms like Meta's Horizon Worlds tap into precisely this evolution, embedding wearable tech and intuitive tools, patiently bringing forth human nuance and naturalness to our digital selves. Virtual inhabitants other than players—those previously static "extras"—are transforming too. Non-player characters endowed with AI from companies such as Inwor…  ( 6 min )
    What I've learned about distributed services
    While I had built distributed software services before, this time was a different scenario altogether and, shall I say, much more interesting! This time was about building a payments processing service for two of the largest companies in the world to interact with one another, in a highly regulated environment. FTP was still involved, but at least the files were not in a fixed-width fields format! This time it was all about the CSV format, but that was not all: our Springboot application had to call existing Java remote services that were distributed across the globe. With that, came the first lesson: you can build vast distributed services on RPC technologies. The main advantage of REST is its HTTP/web interoperability. Because of that, REST APIs have a lot more traction in the western world where an entrepreneurial lattice of companies large and small thrive. But its lack of performance compared to RPC makes REST a less appealing option to large companies building large in-house systems that need to be fast and scalable in order to support their services offerings. Ant Financial uses its very own SOFA = Scalable Open Financial Architecture. SOFA allows for fast, low latency RPC calls at its core, also providing enterprise-ready capabilities such as fault tolerance, governance, observability and extensibility. https://github.com/sofastack  ( 3 min )
    Dark and Light Mode for the non-standard tools
    At work we recently moved. In the office we have automated blinds, these can be manually overwritten, so from my chair, they kind of live their own life. My solution is to switch appearance on macOS depending on the amount of light in the room. Most of the apps support switching between light and dark mode and follow the system settings. Many websites also do this and I even wrote the user story to get one of the products I manage to support this. A few applications however do need a little bit of help. So here I are a few I recently tweaked so they would still be usable in light mode - after all dark mode is the default, we all can agree on that. Do note I use macOS, but the material below should cover Windows as well - well untested from my side, but enough to get you going. Warp can fol…  ( 5 min )
    From Junior to Senior Dev: The Non-Technical Skills That Matter
    When it comes to advancing in the tech world, many developers focus solely on hard skills—coding languages, frameworks, and technical certifications. While these are essential for getting a foot in the door, what truly elevates a developer from junior to senior level in 2025 is a refined set of non-technical skills. In an era dominated by managed IT services, automation, and agile development environments, the traditional role of the developer has expanded. Senior developers are expected to bridge the gap between technical solutions and business objectives. Effective Communication Collaboration and Teamwork Problem-Solving and Critical Thinking Technoholicas often relies on senior-level developers to make critical architecture decisions that align with client goals and long-term IT strategies. Adaptability and Learning Agility Leadership and Ownership Time Management and Prioritization Empathy and Emotional Intelligence The Business Case for Non-Technical Skill Development So, what does all of this mean for business owners and decision-makers? Modern managed IT services are no longer just about keeping the network running. Providers now support: • Developer training and skill-building • Agile workflow implementation • Cloud migration and app modernization • Security-first development practices By outsourcing IT management, small and mid-sized businesses can free up their developers to focus on innovation, while also benefiting from guidance that elevates their talent from junior to senior level.  ( 5 min )

    Strengthening Cybersecurity with a Zero Trust Approach
    Traditional security models based on "trust but verify" are no longer effective. In today’s perimeter-less IT world, Zero Trust is the new standard. It assumes that threats exist inside and outside the network. 🔒 Zero Trust principles: Never trust, always verify: Every user and device is authenticated continuously. Least privilege access: Give users only what they need—nothing more. Micro-segmentation: Reduce lateral movement by isolating critical systems. Real-time monitoring: Detect anomalies and respond instantly. Combining Zero Trust with robust endpoint protection, email security, and threat intelligence leads to a resilient cybersecurity posture. Security is not just about defending—it’s about enabling secure growth.  ( 3 min )
    Scaling to 3 Billion Monthly API Requests Without Microservices: A Pragmatic DevOps Journey
    Hi, I’m Floran Pagliai, the first engineer and now CTO at Weglot. When I joined the company back in 2017, it was still an early-stage startup with just a couple of clients, an MVP coded in Silex, and a big ambition: to simplify website translation without requiring technical skills. Today, we handle over 3 billion API requests per month—and we do it with a monolith. Let me take you through our journey, and why I believe in the power of pragmatic, boring tech to achieve serious scale. I came on board as the first developer when Weglot had just raised its seed round. The infrastructure was basic: Remy, our cofounder, was deploying code via FTP using FileZilla.

    Open/Closed Principle: How to Write Code That Grows Without Breaking
    If every new feature forces you to change what already works… something’s wrong.” Have you ever opened a service and added just one more if? At first, it feels harmless — just one more condition. This is exactly what the Open/Closed Principle (OCP) — the "O" in SOLID — helps you avoid. What is the OCP? In practice, it means you should be able to add new behavior without changing existing code. It’s not just about clean code. It’s about safety, scalability, and long-term maintenance. The less you change working code, the less you risk breaking it. The problem with “if-chains” public double CalculateFee(string paymentType) { Each new method requires changing the original method — and hoping you don’t break what’s already there. This clearly violates OCP — you’re modifying a core function instead of extending the system safely. Applying OCP in .NET public interface IPayment { public class Pix : IPayment { public class Boleto : IPayment { public class Card : IPayment { public class PaymentService { Want to add Apple Pay? That's the power of OCP — change through extension, not modification. Real benefits of applying OCP When not to apply OCP? Practical tip: Apply OCP when you expect varying behavior (payment types, notifications, report generation). Avoid overengineering in simple, stable domains. Final thoughts: OCP protects your code from the future The Open/Closed Principle gives your code a way to evolve without fear, keeping your foundation stable while adding value on top.  ( 4 min )

    Dica de TI: Operadores de incremento e decremento
    Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Nos exemplos a linguagem usada será: Java Além dos operadores citados anteriormente, o operador de incremento é usado para aumentar o valor de uma variável em 1. Existem dois tipos de operadores de incremento: o operador de pré-incremento (++variavel) e o operador de pós-incremento (variavel++). O operador de pré-incremento (++variavel) aumenta o valor da variável em 1 antes de usar a variável em uma expressão. Aqui está um exemplo: int num = 5; int resultado = ++num; //num é incrementado para 6 e depois atribuído a resultado System.out.println(num); // imprime 6 System.out.println(resultado); // imprime 6 Já o operador de pós-incremento (variavel++) aumenta o valor da variável em 1 depois de usar a variável em uma expressão. Aqui está um exemplo: int num = 5; int resultado = num++; //num é atribuído primeiramente à variável resultado e depois incrementado para 6 System.out.println(num); // imprime 6 System.out.println(resultado); // imprime 5  ( 3 min )

    SSDLC – Requisitos de segurança (planejamento)
    Nessa fase, são definidos os requisitos de segurança, funcionais e não funcionais, como as regras que devem ser seguidas, incluindo normas como a LGPD. Além disso, as decisões tomadas aqui influenciam diretamente a arquitetura e o design do sistema, garantindo que a segurança seja considerada desde a estruturação inicial. Algumas perguntas importantes a serem respondidas incluem: Qual é a classificação dos dados de acordo com as políticas da empresa? Isso inclui dados pessoais e sensíveis, e deve ser especificado como cada tipo de dado será tratado. Quem terá acesso aos dados? Detalhar quem tem permissão para visualizar, alterar ou excluir os dados, com base nas políticas de controle de acesso. Políticas de Exclusão: Devemos definir e documentar políticas claras para a exclusão de dados, incluindo como e quando os dados devem ser removidos. Por exemplo, no nosso sistema, temos dados pessoais e acadêmicos das alunas. Quem terá permissão para ver esses dados? Quem pode alterá-los? Quais são as políticas de exclusão aplicadas? Na imagem, podemos ver que a aluna possui dados pessoais (nome, CPF, endereço, data de nascimento) e dados acadêmicos (notas, RA, frequência e histórico escolar). Nota Importante: Dados pessoais: são aqueles que permitem a identificação direta ou indireta de uma pessoa. Voltando ao exemplo, a aluna tem acesso apenas aos seus próprios dados(pessoais e acadêmicos), enquanto a professora tem acesso de visualização e também de edição apenas aos dados acadêmicos de suas alunas, podendo, por exemplo, alterar notas ou incluir justificativas para faltas. Já a administradora tem acesso a todos os dados pessoais, acadêmicos e administrativos de todos os usuários.  ( 4 min )
    Segurança no Desenvolvimento – SSDLC
    Para começarmos a entender o que é SSDLC (Secure Software Development Life Cycle), trouxe uma analogia para vocês. Eu sempre penso em como explicaria algo novo para a minha avó. Então, vamos à analogia e depois à explicação com exemplos. Análise de Requisitos (Planejamento): Nesta fase, você identifica os materiais e requisitos legais necessários para construir a casa, como consultar a prefeitura sobre regras e normas de construção. Arquitetura e Design: Você desenha a planta da casa, escolhendo materiais, planejando entradas e saídas, e definindo medidas de segurança, como alarme e fechaduras. Implementação: A casa começa a ser construída. Você percebe que, além do alarme, precisa adicionar câmeras para garantir mais segurança. Testes: Antes de entregar a casa, a equipe testa o funcionamento das instalações, como eletricidade, alarmes e janelas. Verifica se tudo está em ordem. Implantação: Antes de entregar a casa aos proprietários, engenheiros fazem uma análise para garantir que tudo foi construído corretamente. Se estiver tudo certo, a casa é entregue. Manutenção: A casa está funcionando, mas você precisa fazer manutenções regulares. O alarme ou câmeras podem precisar de atualizações ou trocas devido a falhas descobertas. Bom, agora vamos ao SSDLC :) Como vimos na analogia o SSDLC pode ser considerado uma construção de uma casa, com um Lego, onde cada fase do processo de desenvolvimento de software seguro é uma peça importante que, quando combinada com as outras, forma um software seguro. Ou seja, devemos pensar em segurança desde o início, já no planejamento, e não apenas a partir da codificação. A segurança deve estar presente em todas as fases do ciclo de desenvolvimento. Agora, vamos entender como funciona cada fase desse ciclo.  ( 3 min )
    Segurança no Desenvolvimento: Da Teoria à Prática – Introdução
    Pensando em segurança no desenvolvimento de software, onde geralmente a incluímos? Como pessoa desenvolvedora, posso pensar na fase de codificação, testes e implementação. Mas, se pensarmos um pouco antes, será que o início do desenvolvimento do software é na codificação? Não, sabemos que a codificação não é o começo. Então, por que não pensar e incluir segurança desde o início? SQL Injection teve sua primeira identificação em 1998. Fonte: https://phrack.org/issues/54/8.html Exemplo de report SQL Injection de julho de 2024. Fonte: https://hackerone.com/reports/2597543 Para responder a essas questões, vamos entender como funciona SSDLC (Secure Software Development Life Cycle) e como ele pode ser aplicado tanto em novos projetos quanto em softwares em desenvolvimento. No exemplo, temos uma página de login com os campos "username" e "password". Um agente mal-intencionado (a ameaça) deseja acessar o sistema para obter dados ou privilégios que ele não deveria ter. Ele pode tentar explorar brechas de segurança conhecidas. Quando ele encontra uma falha de segurança por exemplo no login (a vulnerabilidade), ele explora essa falha. Se o agente consegue acessar o sistema, o risco não é só o ato de acessar o sistema em si, mas sim a possibilidade de que a ameaça explore a vulnerabilidade e cause um impacto negativo, como roubo de dados, comprometimento do sistema, ou controle total, especialmente se ele conseguir fazer login como administrador. O risco acontece quando uma vulnerabilidade é explorada, e o impacto desse risco varia conforme o tipo de acesso obtido (por exemplo, um login de administrador representa um risco maior para a empresa). A vulnerabilidade é o ponto fraco que pode ser explorado por uma ameaça, resultando em risco de danos ao sistema.  ( 4 min )

    DIY GPS Tracking with Arduino, SIM800L and Ublox Neo-6M
    After learning how to use sim800l module in my previous project, I decided to create a GPS tracker using the Arduino platform. This project combines a SIM800L module for communication and a Ublox Neo-6M GPS module for location tracking with help of satellites. Making this device is also easy as previous project, just instead of using led, i use a GPS module to get the location and a little changes in the sketch. I measured the current consumption of the device under load and its around 50mAh for sim800l module and 100mAh for gps module. In standby mode, it consumes around 20mAh. With a regular battery(18650 Battery 2500mAh), this device last for around 5 days without charging. As you may now, these kind of devices used in cars or similar places that they has another source of power that he…  ( 7 min )

    Do You Ever Feel Stupid While Learning To Code?
    I remember after I had completed all the Game Development lessons (especially Game Development 1 and 2) on CodeCombat, my final task was to create a minigame in Python and I was left with no comments or help of any kind on how to do that (apart from the lessons I had previously completed from the course). It always left me feeling so overwhelmed that I was unable to code anything, I would feel better the next day and then start coding my game. It should be no secret that learning to code is hard, but it is not helpful to keep thinking like that. It is much more beneficial to think of coding as a challenge as it changes your perception from coding is a struggle to coding is a challenge instead. Coding is a challenge like in a classic adventure game where the hero is going on quests, encounters problems along the way and sometimes has to face a huge and intimidating monster. Nobody knows everything, you learn as you go and coding is a challenge, a challenge you can always improve on! Do you ever feel stupid while learning to code?  ( 3 min )

    📌 Design-First API: Why It Matters for Complex Systems
    Over the years, I’ve learned that a good API doesn’t start with code — it starts with thoughtful design. Design-First API is an approach where you define the API contract before writing any implementation code — typically using specifications like OpenAPI (Swagger). This lets teams agree on the shape and behavior of the API early in the development process. It’s especially powerful in microservice architectures, where clear, stable interfaces between services are critical. Clear separation of concerns Early alignment on requirements across frontend, backend, and cross-functional teams Automation: generate clients, server stubs, validation logic (tools like oapi-codegen help a lot) Living documentation that stays up-to-date with the actual implementation On previous projects — including a B2B wholesale platform and a document templating system — applying the Design-First approach helped us: Speed up development by enabling parallel workstreams Reduce integration bugs Keep service contracts clean and consistent Would you like me to share some practical examples from real-world implementations?

    🌀 From Fibonacci to Focus: How One Sequence Sparked My Coding Journey
    🌱 A Humble Beginning I still remember the very first time I wrote a program — it wasn’t some flashy game or AI model. It was a simple Python script to print the Fibonacci series. At that time, I didn’t even fully understand what recursion or iteration was. All I knew was that the sequence started with 0 and 1, and each new number was the sum of the previous two. That logic fascinated me. It felt like uncovering a hidden pattern in nature, and I was the one bringing it to life with code. a, b = 0, 1 for _ in range(10): print(a) a, b = b, a + b Simple. Elegant. Powerful. After writing that program, I became curious. I wanted to know why the Fibonacci numbers were so famous. That’s when I stumbled upon something amazing — the Golden Ratio, approximately 1.618, which appears not ju…  ( 4 min )

    Big numbers readability in PHP
    You’ve probably encountered situations where you need to write out a large number, and the longer it gets, the harder it is to tell how many digits it actually has. Is 130000000 equal to 13 million, 130 million, or 1.3 billion? At first glance, it’s a mess. $number = 130000000 // This number is 😐? One alternative is to use exponential notation, which makes the magnitude clear: $number = 130e6 // immediately obvious: 130 million 🤘 But for numbers like 133456115, writing it as 133.456115e6 starts to feel counterproductive. Starting with PHP 7.4, there’s a handy new syntax: the numeric literal separator. You can sprinkle underscores into your numbers to improve readability, just like you would in a miliseconds or any other long number that you want to ready clearly: $number = 130_000_000; // 🤩 WOW, that’s clearly 130 million! The underscores don’t change the value or the type: var_dump(130_000_000 === 130000000); // true (integer === integer) var_dump(130_000_000.000 === 130000000); // false (float !== integer) See the RFC for more details: PHP RFC PS: JavaScript supports a similar feature!  ( 3 min )
    Why API design is a mess, and how could a git-native tool help?
    In my dev years and throughout my devrel career, I’ve spent A LOT of time wrangling APIs and devtools (together and separately). API governance is a pain, been for a while. Been there, cursed that, got frustrated - a LOT. Well, just recently I got affiliated with Voiden.md. Given this recent affiliation, I’ve been digging into API tools again. You know, checking what works, what is painful, etc. And I want your take as well. API specs and docs are critical for public-facing microservices, and some internal ones may need them even more. They’re a mess to manage. Currently, we have sources of truth scattered everywhere, specs drifting from code, docs living in another tool, you have some dashboards that nobody checks, and overall, governance is pure chaos.

    Xiaomi RedmiBook: How to Fix Wi-Fi Issues on Linux (Debian distros)
    Hey folks 👋 Recently, I bought a Xiaomi RedmiBook 16 to get more mobility and separate my work environment. Everything was going great, until I booted into Linux and realized the Wi-Fi wasn’t working at all. After some digging, I found out the issue was related to the Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter. It turns out that after installing the OS or updating the kernel, the firmware breaks. Don’t ask me why, but several logs showed the adapter crashing on boot. If you’re facing the same issue, here’s a simple workaround that worked for me on Ubuntu. It should also help on other Debian-based distros like Kali, Mint, Deepin, Xubuntu and etc. When the kernel loads, the adapter crashes due to incompatible or missing firmware. You’ll likely see something like this in dmesg: ath10k_pci 0000:01:00.0: failed to fetch board data for bus=pci… ath10k_pci 0000:01:00.0: failed to load board file… To fix this, you need to manually replace the firmware files on your system. If you try searching online, you’ll find several tutorials recommending replacing the main firmware binary. The problem is, most of them point to the same source, and unfortunately, killernetworking.com has been offline for years. Luckily, I downloaded that binary back then and saved it to a personal drive, since this issue kept happening. I figured it might disappear one day... and it did. So I created a GitHub repository with a .deb package to make things easier. 1 - Clone this repository with this command: git clone https://github.com/rafael-hs/qualcomm-atheros-qca6174-firmware-adapter 2 - Enter the directory and install the .deb sudo apt install ./surface-go-wifi_0.0.5_amd64.deb 3 - Then reboot your system: sudo reboot That's it! After these steps, your Wi-Fi should be up and running. It worked perfectly on my Ubuntu install, and I’ve seen others confirm it on similar distros. If you run into any issues or have another solution, drop a comment. It might help someone else! Thanks for reading and good luck! 🚀  ( 4 min )
    The Future of Learning Is Modular, Voice-Driven, and Personal
    We’ve upgraded everything: medicine, space travel, warfare, communication. But education? Still stuck in the industrial age. Classrooms. Exams. Text-heavy content. One-size-fits-all lectures. It’s all based on a structure built to scale instruction, not understanding. And yet, the world we live in now demands the opposite personalized understanding at scale. Education today still designs for the “average” student, the imaginary median learner who doesn’t actually exist. In The End of Average, Todd Rose explains how institutions fail individuals by trying to serve a generalization. In reality, people learn at different speeds, through different formats, and with different motivations. Designing a system around everyone means it ends up serving no one well.

    How a Developer Can Beat AI (Without Losing Their Mind)
    🤯Feeling Overwhelmed by AI? Everywhere you look, it’s: If you’re just starting out or midway into your coding journey like me, it’s easy to feel like you’re already behind. ✅ What AI is great at: Generating boilerplate code Suggesting syntax Explaining common errors Writing basic functions ❌What AI still sucks at: Understanding real users Solving open-ended problems Designing scalable systems Making smart trade-offs Making a creative work Example: AI can write a “To-Do List App” in seconds. But it won’t know if your users want reminders by email, SMS, or psychic vibes. Here’s how you beat AI: Play the human game. Think like a problem-solver: Ask better questions. Understand the "why" behind the feature. Design for people, not machines. Build with context: Example: AI made the image below using a simple prompt "give me image based on my blog topic" vs the the image generate with proper instruction (i.e. the cover image of this post) Seriously, don’t fight it—use it. Stuck on syntax? Ask AI. Need test cases? Let AI write the first draft. Confused by an error? Let it explain. But always double-check. AI makes stuff up sometimes (you prob already seen that). Want to stay ahead? Get really good at: Problem-solving Communication System design Product thinking These are things AI can’t fake. You don’t need to be faster than AI. You just need to be smarter, more thoughtful, and more human. Let AI do the boring stuff. You focus on building stuff that matters. Liked this post? Share it with a friend who’s stressed about AI. We’re all in this together—let’s build smarter, not just faster. 🧠💻 Got more advice? Drop it in the comments! I'd love to learn more and keep my stress levels down lol.  ( 4 min )

    Tradeoffs Between In-Memory Checks and Database Queries
    To Cache or Not to Cache: Tradeoffs Between In-Memory Checks and Database Queries In software engineering, many real-world problems boil down to tradeoffs, and one recurring decision is whether to query the database multiple times or fetch once and operate on data in memory. This seemingly small architectural choice can shape performance, reliability, and maintainability in ways that are easy to overlook but matter deeply in production. One of the most fundamental and frequently encountered tradeoffs revolves around data access: when faced with needing multiple pieces of information about a single entity (like a user or an order), should we fetch everything once and perform checks in our application's memory, or should we make several targeted queries to the database, asking for specific…  ( 9 min )

So I built one. ✅ A printable incident response checklist for triage ✅ An editable IR playbook aligned with ISO 27001 + AWS best practices ✅ Notification flows using EventBridge, SES, and Slack ✅ A cloud forensics tool matrix to guide acquisition and analysis ✅ Deployment-ready Terraform + Lambda code for alerting automation After publishing my free IR checklist on my blog, I realized many teams (and individuals) still struggle with: Rebuilding IR processes from scratch Responding to findings without a clear comms path Automating triage across teams or accounts I bundled everything I use — templates, scripts, docs — into one focused toolkit. When I started planning IR action plans this would have helped me a lot. You can explore the full breakdown + story behind it here: https://thehiddenport.dev/posts/aws-ir-toolkit/ And if you’re ready to grab it: Download the AWS IR Toolkit on Gumroad (€9) Includes all future updates, and a community where you can suggest changes. 💬 If you've built your own IR tools or want to share feedback — I'm all ears. This is version 1.0, and I plan to keep refining it. Thanks for reading — and stay sharp out there. – Javier  ( 3 min )
    Three Altcoins to Watch Ahead of Trump’s Gala With TRUMP Token Holders
    A new market catalyst is emerging from the intersection of political influence and crypto assets. The team behind the TRUMP memecoin has announced an exclusive gala dinner with former U.S. President Donald Trump, inviting the top 220 holders of the token. The top 25 will also receive a private tour of the White House. This event has generated increased interest in several related altcoins, particularly due to the potential visibility, speculative flows, and network effects surrounding the TRUMP ecosystem. The following three assets are positioned to benefit from this surge in attention. Technical Outlook: Bullish scenario: A breakout above the $0.267 resistance level could open the door to $0.279 as the next target. Bearish scenario: A failure to maintain support at $0.261 could lead to a…  ( 4 min )

    My Early Python Journey: Small Wins, Big Motivation 🚀🐍
    Hey Dev.to friends! 👋 I’m just starting out with Python and honestly, every little step feels like a big victory. I’ve been working through some beginner problems, and while they might look simple to many, for me they’re a huge deal — and I wanted to share what I’ve learned so far. If you’re new to coding or struggling to get started, this is for you. Let’s celebrate the small wins together! Here’s what I tackled recently: Even or Odd Number Checker I learned how to use if-else conditions and handle errors gracefully when the user enters something unexpected. It was my first lesson in writing friendly code that doesn’t just break. Reverse a String Without Built-ins No shortcuts here! I figured out how to reverse a string by looping through each character — it really made me think like a programmer. Counting Vowels in a String This taught me how to loop through strings and do checks. Also, I learned that converting characters to lowercase makes checking easier, which was a neat trick. Celsius to Fahrenheit Converter I applied a real-world formula and added input validation — so the program politely asks for valid numbers instead of crashing. Word Count in a Sentence A simple but powerful way to split strings into words and count them, opening the door to more text processing challenges. Why This Matters Every expert was once a beginner. Small wins add up to big progress. Writing code is as much about mindset as it is about syntax. If you’re learning, don’t underestimate the power of these early steps. They build confidence and a solid foundation to tackle bigger challenges. What’s Next? Thanks for reading my story! 🙏 Happy coding! 💻✨  ( 4 min )

    Why your terminal is boring and what to use instead
    The command line got cool while you were stuck in the 2000s here’s how to level up Introduction Let’s be honest: if you’re still using the default terminal that came with your distro, it’s like showing up to a boss fight with a wooden sword. For a long time, the terminal was just… functional. You open it, run a few commands, maybe even SSH into something if you’re feeling fancy. But in 2025? That’s not enough. The modern dev stack has evolved and so have terminals. We’ve entered the age of GPU-accelerated rendering, autocomplete with AI, hyperconfigurable shells, and terminals that are so pretty they make your IDE jealous.

    Why Your AI Model Thinks You're Weird (But It’ll Still Obey)
    Introduction Ever asked an AI to “make me a sandwich” and gotten a 500-word recipe for a virtual sandwich, complete with ASCII art of bread slices? Or prompted it to “write a love letter to my cat” and received a Shakespearean ode that’s both touching and slightly unhinged? If so, congratulations: your AI model thinks you’re weird. Don’t take it personally—it’s not judging you (well, not exactly). It’s just trying to make sense of the gloriously messy, unpredictable thing that is human intent. In 2025, AI models like me, Grok, or competitors such as GPT-4o and Claude are marvels of engineering, capable of generating text, code, and even creative stories with uncanny accuracy. But the relationship between what you mean and what the AI does is a strange dance of probability, context, and o…  ( 10 min )

    The Silent Shift in Cybersecurity We’re All Part Of
    A few years ago, detecting and responding to cyber threats meant signature-based systems, rule-heavy SIEMs, and a team of analysts swimming in alerts. Fast forward to today—and suddenly, it feels like cybersecurity is quietly undergoing a transformation right under our noses. What changed? We now have systems that can learn normal behavior, adapt to new threats in real time, and even simulate attack paths before they’re exploited. Not perfectly. Not universally. But undeniably. Whether you're deep in blue team operations or building dev tools, chances are you’ve already interacted with some layer of this new approach—whether you realized it or not. This isn’t just about automation. It’s about augmentation. Modern cyber defense strategies aren’t just faster—they’re smarter. But here’s the question that’s been stuck in my head lately: Are we trusting the machines too much, or not enough? Because while AI-based tools are making a real impact—from anomaly detection to adaptive access control—they’re also introducing new risks. Model poisoning. False positives at scale. A widening skills gap. And worst of all, a sense of overconfidence that the system will “catch it.” So where’s the balance? There's a free masterclass happening on 28th May that's diving into this exact space. It’s framed for IT leaders, but it looks like anyone interested in practical insights and forward-thinking strategies would benefit. I’ve already signed up, so if you’re exploring this frontier too, maybe we’ll cross paths there. 👉(https://www.netcomlearning.com/webinar/Cybersecurity-Masterclass-How-AI-is-Redefining-Cyber-Defense?utm_source=devto.com)  ( 3 min )

    First Step Building Solo: Authentication
    In Part 1, I wrote about how I transitioned from working with a team to building solo. Once I made that decision, I needed to start somewhere - and for me, that was authentication. This post covers how I approached it using FastAPI, why I avoided localStorage, and how I made authentication declarative with a custom router. There are many ways to handle authentication, but I chose the most popular and relatively reliable approach: JWT auth. The spec generally assumes two endpoints: One to get an access + refresh token One to get a new access token if the previous one has expired The client needs to store these tokens somewhere and send them with each request—usually in headers. They're often stored in localStorage, which isn’t very secure. But I wasn’t as concerned with security (this isn’…  ( 5 min )
    How AI Tells the Difference Between “Ate” and “Eight” in Speech Recognition
    Imagine someone says a word out loud: “eight” or “ate”. To a human ear, they sound almost identical, most people couldn’t tell them apart without context. So how does an AI system like Google Assistant or Siri know what the speaker meant? That’s where the beauty of speech recognition and natural language processing (NLP) kicks in. Let’s understand it down step by step: When you speak, your voice creates vibrations in the air. A microphone picks up those sound waves and converts them into digital data, essentially, a stream of numbers that represent how your voice changes over time. But AI doesn’t listen to this data the way humans do. Instead, it transforms it into a spectrogram, a visual map of sound over time. It’s like a heatmap that shows: Pitch (high or low sounds) Intensit…  ( 5 min )
    Spring Boot + Redis + Docker: Ultimate Guide to Caching in Java
    With Redis, your Spring Boot app can become faster and handle more traffic without breaking a sweat. This article will show you how to set it up step by step. However, before diving deep into Redis, we need to understand the concept of caching. Cache Cache is a fast, small, temporary storage frequently used by the computer or application to store and access important data. It stores data in a key-value format. By leveraging cache memory, we can minimize database calls, improving application performance since database queries are typically resource-intensive. The main objective of a cache is to speed up the retrieval of data by making a copy of the data in a location that can be accessed faster than the source or database. A cache is a small and fast, efficient memory space that an appli…  ( 9 min )

    How the Richest in Crypto Think
    Nothing reveals a billionaire mindset quite like their spending habits. After all, to earn serious money, you first need to know why you want it. At first glance, it looks like madness - mushrooms on the orbit, banana art, tigers in Lambos. Crypto's wealthiest often seem to turn spreadsheets into spectacle - burning millions on stunts that feel more absurd than strategic. But what if that chaos is the clue? Maybe how they spend their wealth says more about how they earned it - and how they think. And maybe, just maybe, the ability to reprogram markets... comes with the urge to reprogram reality, too. 🛰 $55M to orbit the Earth’s poles (and grow mushrooms) 💰 A $2M treasure hunt - buried across the U.S. 🍌 The banana that became a $5M media weapon Yes.

    From Idea to MVP: Our Food Waste Reduction Platform
    About a month ago, I shared how my internship and final semester project came together perfectly, giving me the chance to dive into Laravel while building a platform to reduce food waste by connecting businesses with surplus food. I’m excited to say we’re nearly done! Over the past few weeks, our team has been polishing the app — fixing bugs, refining the user experience, and preparing for launch. The backend and database will be hosted soon, making the platform live and accessible. Looking Back at the Tech Stack: Backend: PHP Laravel — my internship experience gave me a strong foundation here, and I’ve deepened my understanding of scalable architecture, API development, and ORM relationships. Frontend: React — my teammate has built a clean, responsive UI that complements the functionality we’ve worked hard to develop on the backend, resulting in a seamless user experience across the platform. Database: MySQL — we designed the schema to handle complex relationships efficiently, especially for managing users, food listings, and organization profiles. This project has been both technically and personally rewarding. We’ve approached it like a real-world product, learning through every challenge. What’s Next: Deploying the backend and database online Final usability testing Gathering feedback for improvements If you’ve worked on something similar or have any tips for hosting and scaling Laravel apps, I’d love to connect and learn from your experience. Thanks for following along — more updates soon!  ( 3 min )
    Prompt Debugging Is the New Stack Trace
    What breaking AI workflows taught me about the future of engineering. In traditional software development, when something breaks, you look at the logs. You dig into the stack trace, inspect variables, step through the debugger, isolate the bug. In AI-powered applications, that world is gone. When an LLM fails, there’s often no crash, no error, and no stack trace. Just a subtly wrong response. A hallucination. A weird behavior that’s technically correct but totally wrong for your user. Debugging becomes conversational. And that changes everything. In our product Linkeme, we rely on prompts to: Generate social media content Choose relevant CTAs Compose visual overlays And yet, some of the most frustrating bugs we faced early on didn’t come from bad code — but from poorly constructed prompts.…  ( 4 min )
    What is a Software Firewall?
    Unlike traditional hardware firewalls that protect at the network edge, a software firewall is installed directly on host machines, virtual instances, or endpoints. Its primary job is to inspect, filter, and manage data traffic based on customized security rules. This digital guardian monitors both inbound and outbound connections, blocking suspicious activity and allowing only trusted communication to flow through. Whether it's a server, laptop, or cloud-based instance, a software firewall ensures that devices remain guarded—regardless of where they’re located. Software firewalls function by analyzing data packets using intelligent filtering techniques. They offer controls such as application-level monitoring, port and IP address restrictions, and real-time traffic evaluation. Administrat…  ( 4 min )

    AI Interviews: A Hidden Threat to Corporate Secrets
    Introduction AI powered interview platforms are now common in hiring, asking questions tailored to your skills and analyzing your answers with little human effort. They seem like a smart way for companies to find talent quickly. But a serious worry is starting to surface, especially for developers and job seekers like you: some bad actors might be using these platforms to pull sensitive company information from candidates. What feels like a normal job interview could actually be a sneaky way to collect corporate secrets and sell them to third parties. This is a real issue that needs attention, because many people do not even realize it could be happening to them. Experienced developers, especially those with many years in the industry, are noticing something strange when they go through …  ( 6 min )

    Avoid ObjectId Type for Ambiguous Typing System Across Tiers by Ditching ObjectId in Favor of Strings
    The recipe first Avoid using ObjectId Type for Ambiguous Typing System Across Tiers by favoring Strings instead. This will result in simpler backend types and DTOs that are reusable at the front end without requiring any special tools. The main disadvantage of this approach is a slight decrease in performance, as strings are larger than ObjectIds and can impact fast sorting operations. This scenario originated from a real application. It seems we followed the basic rules in different steps but ultimately failed. It would be great if we had changed the architecture at the start. Our application has a stack consisting of NestJS, Angular, and Mongoose, all written in TypeScript. We successfully implemented reusing typings across tiers, but it appeared complicated. Each tier had its own typing system, which could have been optimized. A clue to the problem is that the type of the primary field _id is ObjectId, a complex type present only on the backend. This made it unnatural for it to be used on both the frontend and backend. Some tools were implemented to reuse these types on ObjectId. New UI types were created, which seemed to improve the application's typing system. However, the application became convoluted, and we didn't want to research the case of using plain string IDs because we thought our approach was correct and it worked everywhere except for MeteorJS projects. If we refused to use the ObjectId type, we could eliminate the need for these tools, new UI types, and even DTOs that work on both frontend and backend. To test this idea, we created a separate project where I implemented the concept. The only disadvantage is the potential impact on MongoDB performance, which I couldn't measure. Additionally, we experimented with meaningful primary IDs where demanded custom solutions where string type is demanded.  ( 3 min )

    What's New 🆕🤯 in PostgreSQL 18 🐘 - a DBA's Perspective
    PostgreSQL just announced 18 beta 1 on May 8, 2025. While some features may still be dropped, it's worth taking a look. PostgreSQL 18 introduces a significant enhancement under the hood with its new asynchronous I/O (AIO) subsystem. According to the official release notes, this feature is designed to increase I/O throughput and to hide I/O latency. It can be enabled via the io_method server variable. For Linux users, this means io_uring can be leveraged, while a worker-based implementation is available for all platforms. The initial implementation focuses on file system reads, including sequential scans, bitmap heap scans, and vacuums.

    400 Lines of code in 20s, all test passed ( llm code generator )
    Hi, I'm the developer of JavaFactory — a code generation tool that automates Java development using LLMs. Most AI code tools I've tried (like Cursor, Copilot, etc.) produce general-purpose code that's often unusable in real-world projects. They might write code quickly, but the result is: unpredictable, hard to maintain, and often completely wrong ( not usable ). So I built something different: A tool where I can explicitly define patterns and precisely control which classes are referenced. Yes, it takes some upfront work to define the rules. But the result? → Code that's testable, maintainable, and consistent with your actual architecture. In this demo, 400 lines of Java code (including tests) were generated in 20 seconds. All tests passed without manual edits. If you're tired of copy-pasting boilerplate and want AI that respects your structure — give this a try. 🔗 GitHub: link JetBrains Marketplace  ( 3 min )

    TypeScript Type Vs Interface? The Answer Is Type!
    Introduction In TypeScript, you can define custom shapes using type aliases or interface. But when it comes to choosing between them, many developers ask: "TypeScript Type vs Interface?" The answer is increasingly clear: use type. While both share similarities, type offers more flexibility, supports complex patterns, and aligns better with modern TypeScript and frameworks. In this guide, you'll learn the differences, strengths, and why type is the better default. Both type and interface define object shapes or function signatures: // Using type type Point = { x: number; y: number }; type SetPoint = (x: number, y: number) => void; // Using interface interface Point { x: number; y: number } interface SetPoint { (x: number, y: number): void } They look and behave similarly here, but the d…  ( 5 min )
    The Accidental Architect: How Developers Are Becoming AI Workflow Designers
    In the ever-evolving world of software development, a seismic shift is underway. Developers, once primarily focused on writing code and building applications, are increasingly stepping into a new role: that of AI workflow designers. This transformation is not driven by a deliberate career pivot but by the rapid integration of artificial intelligence (AI) tools into the development process. These tools are reshaping how software is built, tested, and deployed, turning developers into "accidental architects" who orchestrate complex AI-driven workflows rather than solely crafting lines of code. This blog explores this evolution, examining how AI tooling is redefining developer roles, the skills required to thrive in this new landscape, and the implications for the future of software developme…  ( 9 min )
    TDD is a scam. Grow up and do this instead
    You may remember how much did others tell you to write your tests first, see them fail, and only write your production code after that? It's one of the craziest waste of time in software development, but not for the reasons you may think. The #1 reason your teachers, mentors and your community forced you to write unit tests first was this: get testable code. So, have you just accepted the implied message that if you don't write your tests first, your code will be untestable? Does it feel like you always need to make an extra effort to turn your code testable but you're not exactly sure why? Turns out, long story short, what makes code untestable is side effects.

    What Is Rate Limiting & Why It Matters webdev api security scalability architecture Rate limiting is about controlling how often a client can hit your app or API. It helps prevent abuse, reduce server load, and ensure fair access for everyone. Without it, one bad actor (or even an accidental loop) can overload your system. Every time a client makes a request, your server tracks how many requests they’ve made within a defined time window. If they exceed that limit, the server denies further requests — usually with a 429 Too Many Requests response. Clients can make a certain number of requests per fixed time period (e.g. 100 per minute). Simple but can lead to burst traffic at the start of each window. Spreads the request limit more smoothly over time. Prevents sudden spikes that fixe…  ( 4 min )

    Vector Database Showdown: Architectural Insights for AI Developers
    A Technical Evaluation of Milvus and Chroma DB In the rapidly evolving AI infrastructure landscape, vector databases have emerged as critical components for handling high-dimensional data. This analysis examines two prominent contenders—Milvus and Chroma DB—through the lens of enterprise readiness and developer experience, providing actionable insights for technical teams. Architectural Philosophy & Deployment Performance Benchmarks Milvus achieves 15,000 QPS on 768D vectors with 8ms p95 latency (32-node cluster) Chroma DB manages 2,300 QPS at 28ms latency (standalone instance) The gap widens with complex operations: Milvus' proprietary ANNS algorithms outperform Chroma's FAISS-based implementation by 40% in recall accuracy at 1M+ scale. However, Chroma's memory-mapped indexes demonstrate advantages for frequent schema modifications during development cycles. Ecosystem Integration Native PyTorch/TensorFlow data loaders Automated versioning for vector snapshots Grafana/Prometheus monitoring templates Chroma prioritizes LLM workflows with: LangChain integration out-of-the-box OpenAI embedding API compatibility Dynamic metadata filtering optimized for RAG pipelines Enterprise Readiness Cost Considerations Technical Recommendation Both platforms continue evolving—Milvus recently added GPU-accelerated indexing, while Chroma introduced hybrid scalar-vector search in Q2 2024. Technical leaders should evaluate these systems through the prism of their operational maturity and scalability requirements rather than seeking a universal solution. Note: All benchmark data reflects testing on AWS c6i.8xlarge instances with 500M 512D vectors unless otherwise specified.  ( 4 min )
    How I Learned to Use CSS Transitions Today📘
    Today, I dived into the world of CSS transitions, and I was excited to see how a small piece of code can make a website feel more smooth and interactive. In this post, I’ll share what I learned and how transitions work in CSS. CSS transitions allow you to change property values smoothly (over a given duration) instead of instantly. For example, instead of a button changing color immediately when hovered, transitions let that color change happen gradually. Here’s the basic syntax of a CSS transition: selector { transition: property duration timing-function delay; } property: The CSS property you want to animate (e.g., background-color, width, transform) duration: How long the transition takes (e.g., 0.5s, 1s) timing-function (optional): The speed curve (e.g., ease, linear, ease-in, ease-out, ease-in-out) delay (optional): The delay before the transition starts Hover Me .btn { background-color: #4CAF50; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .btn:hover { background-color: #2E7D32; } When you hover over the button, the background color changes smoothly from green to dark green in 0.3 seconds. You can transition multiple properties like this: .box { width: 100px; height: 100px; background-color: red; transition: width 0.5s, background-color 0.3s; } .box:hover { width: 200px; background-color: blue; } Only animatable properties can be transitioned (e.g., color, background-color, transform, opacity, width, height, etc.) Use transition: all if you want all animatable properties to transition — but use it carefully, as it can affect performance. Combine transitions with pseudo-classes like :hover, :focus, or :active for better interactivity. Learning CSS transitions opened my eyes to how much they can improve the user experience of a website. They're simple to use but make a big impact visually. I’m excited to explore more about animations using @keyframes and the animation property next!  ( 4 min )

Several months ago, the internet was abuzz with the Microsoft CEO Satya Nadella saying, “SaaS is dead.” The conversation started with a question from Bill Gurley about whether Satya was worried that newer startups are building applications with an AI-first approach, which could obfuscate traditional infrastructure like Excel or CRM. Here is Satya’s response: I think, the notion that business applications exist, that's probably where they'll all collapse, right in the agent era because if you think about it, right, they are essentially CRUD databases with a bunch of business logic. The business logic is all going to these agents, and these agents are going to be multi repo CRUD Some people might assume he suggested that AI agents could or would replace SaaS. Howe…  ( 9 min )

    The Death of SQL? The Silent Rise of NewSQL
    In the world of data, change is the only constant. Over the last few decades, SQL (Structured Query Language) has reigned supreme as the go-to language for managing relational databases. Then came NoSQL, challenging the traditional norms with its flexibility and scalability. But today, a new player is emerging quietly yet powerfully: NewSQL. So, is SQL really dying? Is NoSQL losing its charm? And what exactly is NewSQL? Let’s break it down. The Era of SQL: A Quick Recap But as data exploded in volume, velocity, and variety — thanks to social media, IoT, and mobile apps — traditional SQL databases began to struggle with horizontal scalability and flexible schemas. The Rise and Struggles of NoSQL Schema-less design — ideal for unstructured or semi-structured data Lack of ACID guarantees The Death of SQL? The Silent Rise of NewSQL by Abhishek Shakya 🔑 Key Features of NewSQL Databases: Cloud-Native Architecture Real-Time Performance Data Integrity at Scale Simplified DevOps Real-World Use Cases Traditional SQL systems are struggling to keep up with modern demands. NoSQL tried to fill the gap but fell short in consistency and relational data handling. NewSQL is emerging as a modern solution, blending the best of both worlds: the familiarity of SQL and the power of NoSQL. The future isn’t SQL vs. NoSQL. It’s NewSQL — scalable, reliable, and SQL-compatible. If you’re building high-scale, mission-critical apps today, NewSQL might just be the quiet revolution you didn’t know you needed. ✅ Key Takeaways SQL is aging, but not obsolete. NoSQL brought scalability but lacked consistency. NewSQL offers the scalability of NoSQL with the reliability of SQL. NewSQL is powering modern, distributed, cloud-native applications.  ( 5 min )

    Understanding the Distinctions Between Continuous Integration and Continuous Delivery, Agile Methodology, and DevOps
    Software development commonly uses continuous integration (CI), continuous delivery (CD), Agile, and DevOps. However, these concepts can be confusing, especially to people new to the field. Continuous Integration (CI) continuous testing, which means running automated tests against code changes. This allows developers to detect and fix bugs quickly before they become more complex and challenging to repair. Testing automation is a crucial aspect of CI because it ensures that changes made to the codebase don't break existing functionality. Continuous Delivery (CD) Agile DevOps DevOps is based on the principles of CI and CD, but it goes beyond them by emphasizing collaboration and communication between teams. DevOps teams use various tools and practices, such as automated testing and continuou…  ( 6 min )

    AI Makin Pinter, Makin Meresap!
    Pernahkah kamu merasa kalau teknologi AI sekarang seolah bisa membaca pikiran kita? Misalnya, ketika aplikasi musik tiba-tiba merekomendasikan lagu yang sangat cocok dengan selera kita, atau iklan yang muncul selalu terasa seperti dibuat khusus untuk kita. Hal ini terjadi karena AI makin pintar dan makin meresap ke dalam kehidupan sehari-hari. Fenomena ini penting untuk dipahami oleh siapa saja yang menggunakan teknologi digital—mulai dari pelajar, pekerja, hingga pebisnis—karena AI kini sangat memengaruhi cara kita hidup dan bekerja. Kenapa AI bisa makin pintar? bagaimana AI bisa tahu apa yang kita suka? Dampaknya pada kehidupan kita sangat beragam. Contohnya, AI mungkin salah memprediksi preferensi kita, sehingga kita kehilangan kesempatan mendapatkan informasi penting. Seringkali, kita tidak sadar bahwa keputusan sehari-hari sudah dipengaruhi oleh AI karena prosesnya berjalan secara otomatis dan tersembunyi. Lalu, bagaimana kita menyikapi perkembangan ini supaya AI tidak merugikan? Pertama, kita perlu memahami bagaimana AI bekerja dan data apa saja yang kita bagikan. Kedua, gunakan fitur privasi yang tersedia di aplikasi dan perangkat digital. Ketiga, selalu kritis terhadap rekomendasi dan informasi yang diberikan oleh AI. Misalnya, jangan langsung percaya iklan yang muncul, tetapi cek dulu keasliannya agar tidak mudah tertipu. Dengan edukasi dan kesadaran yang baik, kita bisa lebih aman dan cerdas dalam memanfaatkan teknologi AI. Bayangkan kamu sedang mencari pekerjaan, dan platform rekrutmen berbasis AI merekomendasikan pekerjaan yang tidak sesuai dengan minatmu hanya berdasarkan data lama yang pernah kamu input. Apakah kamu akan mengikuti saran itu begitu saja? * Ini contoh nyata bagaimana AI yang makin meresap bisa memengaruhi keputusan penting dalam hidup kita. Oleh karena itu, yuk mulai kenali AI yang kamu gunakan, atur privasi dengan baik, dan jangan takut bertanya serta belajar supaya AI benar-benar menjadi alat yang membantu, bukan justru mengatur hidup kita tanpa kita sadari.  ( 4 min )

    🚧 Understanding CORS: Cross-Origin Resource Sharing for Web Developers
    If you’ve seen this in your console: “Access to fetch at ‘https://api.example.com’ from origin ‘https://yourapp.com’ has been blocked by CORS policy…” You’re not alone. Let’s dive into what CORS is, why it exists, and how to fix it. CORS? CORS (Cross-Origin Resource Sharing) is a browser-enforced security feature that prevents your frontend app (served from one origin) from accessing resources from another origin unless explicitly allowed by the server. This behavior stems from the Same-Origin Policy, which is designed to help prevent cross-site attacks. How CORS Works When your frontend makes a request to another origin, the browser sends an Origin header: Origin: https://myapp.com If the server responds with: Access-Control-Allow-Origin: https://myapp.com Preflight Requests For requests using methods like POST, PUT, or custom headers, the browser sends a preflight OPTIONS request to check if it’s safe. If the server doesn’t respond correctly, the browser cancels the actual request. Backend Config: Enabling CORS Here’s how to configure CORS in common backend frameworks: 🟢 Express.js const cors = require('cors'); 🐍 FastAPI app.add_middleware( https://myapp.com"], "], "], ❗ Common CORS Issues ❌ Missing Access-Control-Allow-Origin header ❌ Wildcard origin (*) used with credentials ❌ Server doesn’t respond to OPTIONS preflight 🧠 Dev Tips Use tools like http-proxy-middleware or Vite’s proxy config during local development. Never disable CORS in production — configure it properly. ✅ Final Thoughts CORS is not a bug — it’s a feature 🔐 Understanding how it works makes you a more confident full-stack developer and prevents hours of frustrating debugging. 💡 Got a CORS horror story or a helpful trick?

Now, we're tackling the juicy stuff; the advanced patterns that'll save your sanity when your enterprise Angular app starts growing. (⏱️ Est reading time: 9.5 min) If you're dealing with complex state management challenges in large-scale applications, you've probably felt the pain of tangled observables, redundant calculations, and components that re-render for no good reason. Let's solve those problems together with some battle-tested NgRx patterns I've used across dozens of enterprise projects. You'll use selectors to derive data without doing extra work and thanks to NgRx's memoization, your app stays fast even when the state gro…  ( 9 min )
    NgRx State Management Across Angular Modules
    Part 2: Structuring Shared State in Large Applications In Part 1, we explored the basics of NgRx and why a centralized state can help tame complexity in modern Angular applications.

(⏱️ Estimated reading time: 4.5 minutes) Imagine you're building a house with several rooms. Each room serves a different purpose, but everyone in the house needs to know if it’s day or night, hot or cold, or if someone’s at the door. In Angular, each feature module is like a room, self-contained, but part of the same living space. Now imagine that instead of a shared thermostat or central lighting control, every room make…  ( 5 min )
    Background jobs with Rails 8 are delightful
    Article originally published here (image doesn't work well here) : https://alsohelp.com/blog/background-jobs-in-rails-8-are-delightful There's one thing I forgot to mention about my Rails 8 opinion last time : it's how background jobs are handled in Rails 8. Here's what it looks like on my current project : (image) Most web frameworks completely underestimate how background jobs are valuable. Honestly I always need a way to handle background jobs, on every new web project. Forgot password email ? => background task to send the email Clean image asynchronously ? => background task to clean the image And so on. IMHO A good way go see if a framework is mature enough is "are background jobs already included from day 1". Why it is so good with Rails 8? Because you don't have to care about : it's already included. From what I've read, it's not possible with other frameworks - outside Laravel. The Database is already backed The Dashboard is already included (!) And, of course, it's damn easy to hook any kind of job inside the framework itself. All I had to do is to protect the route, so that only the admin can view it. You don't have to care about the JS/CSS, because as long as you keep "propshaft" as gem, it will work. The beauty (again) is that I don't use propshaft myself. I use Vite. This is Rails deep integration : even if you don't use the default frontend management, external gem will work with your product. Of course "background jobs" means "take another thread than the one of the web server". So there's a tiny configuration locally (Thank you Matt Brictson for your bin/dev Rails 8 shine not only for the things previously mentionned, but also thanks to mission control. It gives you very elegant, monitor-able background jobs, right from day one, with full support and upgrades of the Rails maintainers. Close from silver bullet ;)  ( 4 min )
    The Basics of TypeScript
    TypeScript - sounds familiar to another coding language called JavaScript, right? Well, it's a language based on JavaScript; the only difference is that it focuses on type safety. This makes it easier to catch errors before you run your code. This makes working on big projects easier to manage and improves the coding process by making it smoother and more reliable. Luckily, it's not too hard to learn as long as you have a basic understanding of JavaScript. JavaScript was created by Microsoft and released in October 2012 How do I start? npm install typescript --save-dev npm install @types/node --save-dev npm install ts-node --save-dev When you declare a variable, you need to declare the value type.

    Thoughts after 6 months coding with AI
    I no longer think you should learn to code. Amjad Masad (CEO of Repit) I’ve been coding for about 16 years and working professionally for over a decade. After months of testing AI-assisted tools and “vibe coding” in early 2025, I can confidently say: that statement couldn’t be further from the truth. Sure, LLMs have pulled off some amazing things.

Let’s take a look at things that have happened before, because this is not the first time we face a statement like this; back in the late 50’s - early 60’s COBOL emerged stating that it would allow people without traditional programming backgrounds ( like business professionals, managers, and analysts ) …  ( 10 min )
    Go (11) - Channels & Concurrency
    Concurrency VS Synchronization Synchronous code When code executes line by line in order, one thing at a time is called synchronous. It is simple, but sometimes might not be very efficient. func main() { // block 1 x := 10 x++ fmt.Printf("x = %d", x) // block 2 y := 20 y-- fmt.Printf("y = %d", y) } Check the code blocks in the above example. As you can see, the code lines in block 1 should execute in order. The code lines in block 2 should also execute line by line. But blocks 1 and 2 have no dependency on each other. So, we can run them separately on two CPU cores. This is called running in Parallel. It increases efficiency. In Golang, it is easy to write concurrent code. func main() { // some code go funcName() // rest of the co…  ( 6 min )
    Segmented Accumulation by Condition — From SQL to SPL #30
    Problem description & analysis: The ID field of a certain database table is used for sorting, the logic field is used for conditional judgment, and val is used for segmented accumulation. Task: Now we need to add a calculated column output. When logic==true, output is set to 1. Otherwise, output is accumulated and the value is the output of the previous row + val. SQL: with table1 as ( SELECT *, countif(logic) over win1 as logic_run FROM example_data window win1 as (order by id rows between unbounded preceding and current row) ) SELECT *, sum(val) over win2 as sum_over, sum(if(logic,1,val)) over win2 as output from table1 window win2 as (partition by logic_run order by id rows between unbounded preceding and current row) SQL requires multiple window functions and subqueries to indirectly implement cumulative calculations, which is cumbersome in terms of code. SPL: SPL provides syntax of relative positions that allows for direct accumulation. ✍🏻 Try.DEMO A1: Load data.

    Extracting a General-Purpose EventBus Component from DolphinScheduler: Supporting Delayed and Event-Driven Execution
    1. Background and Motivation Although Google Guava’s EventBus is already quite convenient, I wanted to build something more extensible — a component that not only functions as an EventBus but also supports delayed events out of the box. While exploring the Apache DolphinScheduler project, I found its built-in eventbus component to be a well-written and efficient solution. It inspired me to extract and adapt it for use in our own business systems. Thanks to DolphinScheduler’s open-source nature, this component can now be conveniently reused with minimal overhead. Let’s walk through how to extract it and run a working demo. First, we define a base interface for all events: public interface IEvent { } To support delayed execution, we introduce an abstract class AbstractDelayEvent that exte…  ( 5 min )

    Por dentro da estrutura de dados dicionário (hash map)
    Em programação, um dicionário (também chamado de mapa ou hashmap) é uma estrutura de dados que armazena dados em pares de chave-valor, onde as chaves são usadas para acessar os valores. É como uma lista onde os elementos são acessados por nomes (chaves) em vez de índices numéricos. As chaves do dicionário são usadas como índices para localizar o valor associado. Ao invés de percorrer a coleção inteira para encontrar um valor, o dicionário usa a chave para calcular um índice na tabela hash. Essa chave é passada para uma função hash, que gera um valor numérico (o índice na tabela hash). Para exemplificar, vamos armazenar o valor do quilograma de cada fruta dentro do dicionário.

    Pseudo-element yang Wajib Diketahui
    Pseudo-element yang Wajib Diketahui Pseudo-element secara bahasa artinya Element Semu, alias element yang samar atau tersembunyi. Pada beberapa elemen HTML ada yang membawa elemen semu seperti elemen input yang membawa elemen semu placeholder. Kalau kita memberikan styel color ke input, maka style tersebut akan diterapkan ke hasil inputan kita dan bukan ke placeholder. Disini lah peran pseudo-element sebagai selector ke placeholder. Pseudo-element ciri khasnya diawali dengan titik dua dua di depan. Jadi untuk placeholder selectornya menjadi ::placeholder. Contoh: input::placeholder { color: silver; } "Bagaimana cara mengetahui ada Pseudo-element apa saja?"

    Closures in JavaScript
    Closures in JavaScript occur when a function retains access to variables from its lexical scope, even after the outer function has finished execution. This allows functions to "remember" values and maintain state. 🔹 Simple Example: function outerFunction() { let counter = 0; // Local variable return function innerFunction() { counter++; // Inner function remembers 'counter' console.log(counter); }; } const increment = outerFunction(); // Returns innerFunction increment(); // 1 increment(); // 2 increment(); // 3 🔹 Explanation: outerFunction() defines a local variable (counter). innerFunction() modifies counter, but the outer function has already executed! However, innerFunction() retains access to counter due to closure behavior. Each call to increment() updates the retained counter, demonstrating persistent state. Closures are useful for encapsulation, maintaining private variables, and creating efficient event handlers. 🚀  ( 3 min )
    Hands-On: Building a High-Performance Message Queue in Go (Inspired by NSQ)
    1. Why Build a Message Queue from Scratch? Message queues are the unsung heroes of distributed systems—think of them as traffic cops directing data between services. They decouple apps, handle async tasks, and smooth out traffic spikes. NSQ, a lightweight, Go-based queue from Bitly, caught my eye for its simplicity and speed, making it perfect for small-to-medium projects. So why rebuild it? Two reasons: Learning by Doing: Nothing beats rolling up your sleeves to grok how queues tick. Customization: Need priority messages or a leaner persistence layer? DIY lets you tweak it your way. This tutorial walks you through coding an NSQ-inspired message queue in Go. It’s aimed at devs with 1-2 years of Go experience—folks comfy with goroutines and channels but itching to tackle distributed s…  ( 9 min )

    Print Smarter in Ruby - Know When and How to Use Each Method
    If you've ever stared at a blob of console output wondering what the hell you just printed, you're not alone. Ruby gives you a handful of ways to print stuff, but knowing when to use which one is the real trick. In this post, we'll go through the five most common ways to print output in Ruby, plus one gem that makes your console look like it's had a glow-up. puts: Standard Output with Automatic Newlines puts is your go-to for dumping simple output to the console.

    Justin Sun to attend Trump's dinner with memecoin backers
    After weeks of speculation among crypto enthusiasts and news outlets, Tron founder Justin Sun has claimed he owns the wallet that purchased the largest amount of Donald Trump’s memecoin, allowing him to qualify for a dinner and reception with the US president. In a May 19 X post, Sun said he had received an invitation to attend Trump’s dinner at his golf club outside Washington, DC, as part of a reward for the top 220 memecoin holders. The Tron founder claimed he controlled the top wallet on the TRUMP token leaderboard under the username “Sun,” which held roughly $19 million worth of the memecoin at a price of $13.20. According to Sun, he plans to network at the May 22 memecoin dinner, “talk crypto,” and “discuss the future” of the industry. It’s unclear why the Tron founder chose to annou…
    Bitcoin open interest hits record high as bulls stampede toward new BTC price highs
    Key takeaways: Bitcoin futures open interest hit a record $72 billion, signaling rising use of leverage among institutional investors. $1.2 billion in shorts at $107,000 to $108,000 are at risk of liquidation, boosting BTC’s breakout odds. The aggregate open interest in Bitcoin (BTC) futures surged to a record high on May 20, raising questions about whether bearish positions are now at risk. Despite repeated failures to break above the $107,000 level since May 18, the sheer volume of leveraged positions could propel Bitcoin to a new all-time high.

    Ethereum price gained 90% the last time this indicator turned bullish
    Key Takeaways: Ethereum is forming a bull flag on the daily chart, with a potential breakout above $3,600. If ETH reclaims the 2-week Gaussian Channel mid-line, a 90% rally could occur. Ethereum (ETH) price is consolidating between $2,400 and $2,750 on its daily chart, forming a bull flag pattern with sights on the $3,000 to $3,100 resistance zone.

    Bancor files patent infringement lawsuit against Uniswap over DEX tech
    Bancor, the creator of a smart contract-based automated market maker, is suing Uniswap for patent infringement, alleging the decentralized finance exchange has used its technology without permission and profited significantly from it. According to the May 20 announcement of the lawsuit, Bancor designed the technology in 2016 and patented it in January 2017. The technology underpins the “constant product automated market maker,” which involves using mathematics to add or withdraw resources from a liquidity pool. The application subsequently led to two issued patents. Bancor alleges that Uniswap used the invention to create its protocol, launched in November 2018. The two organizations are considered competitors in the sector of decentralized finance (DeFi). “When an organization continuousl…
    Bitcoin ready to ‘vaporize’ shorts once price discovery above $110K begins
    Key takeaways: An end-of-month Bitcoin price close above $102,400 would set the highest monthly close ever, proving the bull market continues at a rapid pace. Over $3 billion in Bitcoin short positions are vulnerable above $107,000, creating a “liquidation magnet” that could send BTC price to new highs. Bitcoin (BTC) is 11 days from potentially setting its highest monthly candle close in history. After achieving a record weekly close of $106,407 on May 18, BTC could secure a new monthly high by closing above $102,400 this month. Bitcoin 1-month chart.

    Coinbase CEO's journey from no 'political causes' to hiring DOGE staff
    Five years ago, Brian Armstrong wanted employees of his cryptocurrency exchange to refrain from expressing political views at work. Now, the Coinbase CEO seems to be open to involvement with Republican figures, including members of US President Donald Trump’s inner circle. In a May 13 X post, Armstrong said members of the Department of Government Efficiency (DOGE) team, spearheaded by Elon Musk, though not set up as an actual department, would be welcome to implement cost-cutting changes at Coinbase after leaving the US government. Armstrong offered to set up an accelerated onboarding process with the exchange, responding to an interview in which at least one DOGE staffer felt ostracized from Harvard University, where he had been enrolled. “If you are looking for your next mission after s…

    SEC crypto task force to release first report 'in the next few months'
    US Securities and Exchange Commission (SEC) Paul Atkins appeared before lawmakers in one of his first hearings since becoming chair of the financial regulator, addressing questions about his plans for the cryptocurrency industry. In a May 20 hearing discussing oversight of the SEC, Atkins reiterated his pledge to make regulating digital assets a “key priority” while chair. In response to questions from North Carolina Representative Chuck Edwards, the SEC chair did not directly answer how much of the regulator’s funds were used to support the crypto task force headed by Commissioner Hester Peirce, and said its findings were “still under development.” “We should be having something here in the next few months with proposed steps forward,” said Atkins in response to the task force’s first report.  The SEC chair’s appearance at the oversight hearing was one of his first since being sworn into office in April. Nominated by Donald Trump, Atkins, also a former commissioner, was seen by many lawmakers and those in the digital asset industry as someone who could radically change the SEC’s approach to crypto.  This is a developing story, and further information will be added as it becomes available.
    Argentina's Milei shuts down task force investigating LIBRA scandal
    Argentine President Javier Milei has dissolved a task force established to investigate the fallout from LIBRA, the scandalous cryptocurrency project the head of state promoted on his social media channel before it crashed to zero.  The Investigative Task Force (ITU) was dissolved via a May 19 decree signed by Milei and Justice Minister Mariano Cúneo Libarona, government documents revealed.  “The Research Task Unit is dissolved” after completing its mandate, the translated version of the decree read.

    The crypto market values chains more than standalone applications
    Opinion by: Hatu Sheikh, founder of Coin Terminal Although blockchains and DApps are critical, crypto industry stakeholders often prioritize applications based on adoption principles and revenue distribution. DApps won't function without their underlying chains. The markets must uphold blockchains for long-term value generation. The value perspective is wrong  Blockchains and DApps should work collaboratively to coordinate their functions for better usability. Instead, analysts create a binary between chains and DApps based on Web2's structural frameworks. In “Fat Protocols,” Joel Monegro argued that value within the internet stack comprises "thin" protocols and "fat" applications. In other words, investing in the underlying protocol technologies like TCP/IP, HTTP, and SMTP gives lower ret…
    Senate stablecoin vote splits Democrats amid concerns over corruption
    US Senate Democrats are getting flak after they helped move stablecoin legislation ahead for discussion on the Senate floor. On May 19, 16 Democratic senators broke from the party line to pass a motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Some of the same Democrats had held up the bill in early May when they withdrew support, citing corruption concerns over President Donald Trump’s cryptocurrency dealings. The bill’s opponents hailed lawmakers’ refusal to support it but were soon taken aback when the senators reversed their position. The lightly amended legislation contained no provisions regarding World Liberty Financial, the Trump family’s crypto venture. Some activists have said that the Democrats supporting the bill should be ousted in the u…
    Robinhood proposes SEC rules for tokenized real-world assets
    Robinhood submitted a 42-page proposal to the US Securities and Exchange Commission (SEC), calling for a national framework to regulate tokenized real-world assets (RWAs). The brokerage is seeking to modernize financial infrastructure by making tokenized assets legally equivalent to their traditional counterparts and enabling compliant onchain settlement, Forbes reported on May 20.

    India’s Supreme Court urges government to regulate cryptocurrency
    India’s Supreme Court has questioned the government’s lack of regulatory clarity on cryptocurrencies despite imposing taxes on digital assets like Bitcoin. According to Indian legal news outlet LawChakra, the country’s Supreme Court expressed concern over the growing use of Bitcoin (BTC) and other cryptocurrencies while remaining largely unregulated. “This is a whole parallel economy running with such coins and is a danger to the economy of the country,” Justice Surya Kant reportedly said during a recent hearing related to an ongoing investigation into a Bitcoin transaction. Kant further highlighted that while the government has implemented crypto taxation, it has failed to regulate the space. “If you can tax it at 30%, also please regulate it as you have recognised it by taxing it,” the j…
    Binance seeks to dismiss $1.76B FTX lawsuit, blames SBF for collapse
    Binance has filed a motion to dismiss a $1.76 billion lawsuit brought by the FTX estate, accusing the defunct crypto exchange of trying to deflect blame for its own failure. Filed on May 16 in the Delaware Bankruptcy Court, Binance’s legal team called the suit “legally deficient,” stating that FTX’s collapse was not triggered by market manipulation or hostile action but by internal misconduct. “Plaintiffs are pretending that FTX did not collapse as the result of one of the most massive corporate frauds in history,” the filing said, pointing to Sam “SBF” Bankman-Fried’s conviction on seven counts of fraud and conspiracy. FTX’s estate alleges that Binance received billions in crypto during a 2021 buyback deal, funded improperly with customer assets. Binance rejects this claim, stating that “…

    Bitcoin is signaling a golden cross — What does it mean for BTC price?
    Key takeaways: Bitcoin is nearing a golden cross that led to 45–60% price rallies in the recent past. Fundamentals like rising M2 supply and easing trade tensions support a bullish outlook. Bearish divergence and overbought conditions show there’s still a risk of BTC falling below $100,000. Bitcoin (BTC) will likely confirm a “golden cross” on its daily chart by the end of May, a technical pattern whose occurrences in recent years often preceded rallies.

    South Korean presidential front-runner proposes won-based stablecoin
    South Korea’s Democratic Party leader Lee Jae-myung proposed creating a stablecoin tied to the Korean won to prevent capital outflows and strengthen national financial sovereignty. Speaking during a recent policy discussion, Lee argued that a won-based stablecoin would allow South Korea to retain wealth domestically while reducing reliance on foreign-issued digital assets like USDt (USDT) and USDC (USDC), according to The Korea Herald. Currently, South Korean law prohibits the issuance of domestic stablecoins, forcing local exchanges to rely on US dollar-based alternatives. Between January and March, crypto exchanges in the country recorded 56.8 trillion won ($40.8 billion) in asset outflows, nearly half of which were linked to foreign stablecoins, the report said. “We need to establish a …
    How $330M was stolen without hacking: The dark power of social engineering
    The $330 million attack: A stark reminder of social engineering’s power A major crypto theft has sent shockwaves through the industry, with $330 million worth of Bitcoin (BTC) stolen. Experts say this was a social engineering attack and not a technical hack.  Investigations led by blockchain analyst ZachXBT suggest the victim was an elderly US citizen who was manipulated into granting access to their crypto wallet. On April 28, 2025, ZachXBT detected a suspicious transfer of 3,520 BTC, worth $330.7 million.  The stolen BTC was quickly laundered through more than six instant exchanges and converted into the privacy-oriented cryptocurrency Monero (XMR). Onchain analysis shows the victim had held over 3,000 BTC since 2017, with no previous record of s…
    Genesis files dual lawsuits to claw back $3.3B from DCG, Barry Silbert
    Genesis has launched a pair of lawsuits against its parent company, Digital Currency Group (DCG), and its CEO, Barry Silbert, accusing them of fraud, reckless mismanagement and siphoning more than a billion dollars in value from the now-bankrupt crypto lender. On May 19, the Delaware Court of Chancery unsealed a complaint detailing how DCG allegedly used Genesis as a corporate ATM, draining funds through self-serving loans and concealed transfers while presenting a false image of financial health. Through their court-appointed Litigation Oversight Committee (LOC), Genesis creditors claim that over a million digital coins — worth about $2.1 billion — were funneled away, even as Genesis edged toward collapse. As per the complaint, Genesis creditors are still owed around $2.2 billion worth of…

    SEC’s Crenshaw says agency playing ‘regulatory Jenga’ with crypto
    The US Securities and Exchange Commission’s sole Democratic Commissioner has said the agency is “playing a game of regulatory Jenga” with its approach to the crypto industry and market regulation under the Trump administration. In May 19 remarks at the SEC Speaks event, Commissioner Caroline Crenshaw cautioned against what she described as a dangerous dismantling of “discrete but interrelated rules” on crypto and the wider market. She likened market stability to a “Jenga tower” that the agency’s rules had “carefully developed over the years,” which could topple if some rules were removed. In addition to a lamentable loss of staff, Crenshaw said the SEC has used staff guidance to effectively reverse rules without proper analysis or public comment, particularly around crypto “Our statements…
    Binance wants arbitration for all members of securities class suit
    Crypto exchange Binance has asked a US federal judge to send all members of a class-action lawsuit alleging it sold securities to arbitration, arguing that the group waived their ability to form a class action under the company’s terms. The exchange said in a May 16 filing to a New York federal court that its terms of service, which it claimed the class group agreed to, has a clause that users agree to arbitrate all claims, along with a clause preventing users from launching class actions against the crypto exchange. “The Court should hold that Plaintiffs are required to arbitrate claims that accrued after Feb. 20, 2019, even if the Court adheres to its initial decision as to claims that accrued before then and that the class-action waiver in the 2019 Terms of Use is enforceable for all of…
    JPMorgan boss says bank users can soon buy Bitcoin
    Jamie Dimon, the CEO of JPMorgan, said his bank will soon allow its clients to buy Bitcoin, but it won’t custody the cryptocurrency. “We are going to allow you to buy it,” Dimon said at JPMorgan’s annual investor day on May 19. “We’re not going to custody it. We’re going to put it in statements for clients.” CNBC reported that Dimon also remarked on his long-held skepticism about crypto assets, pointing to their use in money laundering, sex trafficking and terrorism. “I don’t think you should smoke, but I defend your right to smoke. I defend your right to buy Bitcoin,” he said. Michael Saylor comments on Dimon’s announcement. Source: Michael Saylor JPMorgan will offer clients access to Bitcoin (BTC) exchange-traded funds (ETFs), CNBC reported, citing sources familiar with the situation. Until now, the firm has limited its crypto exposure primarily to futures-based products, not direct ownership of digital assets.

Spot Bitcoin ETFs in the US have seen significant adoption, with almost $42 billion in total aggregate inflows since they launched in January 2024.  Dimon’s Bitcoin bashing history Dimon has long been skeptical of Bitcoin, labeling it a scam that he had no interest in buying in 2018 and calling it “worthless” during the 2021 crypto bull market. “I’ve always been deeply opposed to crypto, Bitcoin, etc.,” he said during a Senate Banking Committee hearing in 2023. “The only true use case for it is criminals, drug traffickers, money laundering, tax avoidance.” “If I were the government, I’d close it down,” he said. At the 2024 World Economic Forum in Davos, Switzerland, Dimon said Bitcoin “does nothing. I call it the pet rock,” which came after the asset topped $100,000 for the first time.   Magazine: Arthur Hayes $1M Bitcoin tip, altcoins ‘powerful rally’ looms: Hodler’s Digest
    US Senate moves forward with GENIUS stablecoin bill
    The US Senate has voted to advance a key stablecoin-regulating bill after Democrat Senators blocked an attempt to move the bill forward earlier in May over concerns about President Donald Trump’s sprawling crypto empire. A key procedural vote on the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed in a 66-32 vote on May 20. Several Democrats changed their votes to pass the motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Republican Senator Cynthia Lummis, one of the bill’s key backers, said on May 15 that she thinks it's a “fair target” to have the GENIUS Act passed by May 26 — Memorial Day in the US. The US Senate voted 66-32 to advance debate on the GENIUS stablecoin bill. Source: US Senate The GENIUS Act was introduced on Feb. 4 by US Senator Bill Hagerty and seeks to regulate the nearly $250 billion stablecoin market — currently dominated by Tether (USDT) and Circle’s USDC (USDC). The bill requires stablecoins be fully backed, have regular security audits and approval from federal or state regulators. Only licensed entities can issue stablecoins, while algorithmic stablecoins are restricted. Several Democratic senators withdrew support for the bill on May 8, blocking a motion to move it forward, citing concerns over potential conflicts of interest involving Trump’s crypto ventures and anti-money laundering provisions. Related: Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report The bill was revised soon after to receive enough bipartisan support to proceed to a vote.

    Anza, a Solana blockchain infrastructure firm spun out of Solana Labs, has proposed a new proof-of-stake consensus called Alpenglow that it claims would be “the biggest change to Solana’s core protocol” and compete with current internet infrastructure. “We believe that the release of Alpenglow will be a turning point for Solana.

    Everything you need to know about estimating AI’s energy and emissions burden
    When we set out to write a story on the best available estimates for AI’s energy and emissions burden, we knew there would be caveats and uncertainties to these numbers. But, we quickly discovered, the caveats are the story too.  This story is a part of MIT Technology Review’s series “Power Hungry: AI and our…  ( 33 min )

    OWASP® Cornucopia 2.2 & Copi - A Game Engine for OWASP® Cornucopia Threat Modeling
    The pandemic drove a considerable increase in fully remote teams, which made card games quite difficult to organize. Therefore, in 2022, Grant Ongers was willing to bet a dinner at a fancy vegan restaurant that his former colleague Toby Irvine wouldn't be able to build a fully fledged and online game engine based on the game Cornucopia (from the OWASP® Foundation) over the weekend. A weekend later, Copi was born, and Grant lost the bet. Elixir and Phoenix, 3 years later, Copi is nearing almost 10.000 monthly users. You can read more about Toby's story on the Secure Delivery Blog. There is now a new release of OWASP Cornucopia 2.2 to celebrate a new milestone in the project's history. https://github.com/adamshostack/eop Finally, if you have stringent security policies that don't allow you…  ( 5 min )

    Building a Gold (XAUUSD) Trend Tracker with Python and SQLite
    XAUUSD is a symbol used in Forex trading to indicate the number of US dollars needed to buy one ounce of gold. Other abbreviations such as EURUSD indicate the exchange rate of national currency pairs while XAUUSD shows comparison between the price of the precious metal and the rate of the US dollar. It is possible to buy gold as a physical commodity at banks or from dealers. Gold is often used by governments that have a large gold reserve to protect the value of their currency; that’s why it is traded on the Forex market. I chose XAUUSD due to high volume of trading together with an extensive amount of historical and real-time data available. It is also not specific to any one nation, economy, or business; rather, it is globally essential. It is more intriguing examining how the …  ( 5 min )
    Gestão de Projetos, Frameworks e Desenvolvimento: o elo invisível do sucesso
    A gestão de projetos é, cada vez mais, um pilar técnico dentro das organizações modernas. Não adianta ter um time que domina frameworks de ponta ou uma stack atualizada se os projetos caminham sem clareza, priorização e cadência. Em muitos casos, não é a tecnologia que trava o time é a ausência de uma gestão estruturada. Empresas como o Nubank, por exemplo, entenderam desde cedo a importância de ciclos curtos e times autônomos. Ao adotar uma variação do modelo Agile, com squads multidisciplinares e foco em entregas iterativas, conseguiram escalar seus produtos mesmo utilizando uma linguagem funcional como Clojure, considerada pouco comum no mercado. Não foi apenas a escolha da linguagem que impulsionou o sucesso, mas como os projetos foram organizados para extrair o máximo do time técnico.…  ( 4 min )

    Exploring Security Risks and Vulnerabilities in Model Context Protocol (MCP): The Emerging Challenge for AI Systems
    Alright, folks, welcome back to the series of Model Context Protocol! In Part 2: Looking Under the Hood, we took a delightful little spelunking trip into the guts of MCP, marveling at its STDIO and SSE transport mechanisms, and even peeked at the shiny new OAuth 2.1 and Streamable HTTP features. It all looked so promising, so... functional. Well, today we're trading our hard hats for tinfoil ones. We're about to wade into the swampy, infested, and quite frankly, terrifying security landscape of MCP. If Part 2 was about how MCP works, Part 4 is about how it breaks... spectacularly.

    My First Steps in JavaScript: Understanding Variables
    Introduction Imagine stepping into a vast digital sandbox, ready to build anything you can dream of in a JavaScript program. In this creative space, variables are your essential building blocks and storage containers. Just like in a sandbox game where you need places to keep your tools, materials, and the scores of your players, variables in JavaScript are fundamental for holding all the information your program needs to work. They are the named boxes where you store data – from simple numbers and text to more complex structures that bring your digital world to life. In this post, we'll dig into what JavaScript variables are, why they're so crucial, how to create and name them, and how you can start using them to shape your own interactive experiences.

    Azure App Service - Hidden Network Trap
    Introduction A few weeks ago, I was asked to investigate intermittent database connection failures affecting one of two Azure App Service instances. Both instances shared the same App Service Plan for a client, and—crucially—had been running smoothly for five weeks before these issues appeared. Interestingly, all development ("lower") environments were unaffected; only the production environments were experiencing failures. Each app used its own Azure Storage account and Azure SQL database. Both App Services were in production. The first app was failing to connect to its storage account, while the second was failing to connect to its Azure SQL database. The logs didn’t reveal anything unusual—just connection failures. Since the apps were already down, I decided to restart them, hoping a …  ( 4 min )

    Python vs SQL: Which is Best for Querying and Cleaning Data?
    When working with data, we are familiar with two tools: SQL and Python. Both are important for data professionals, but they serve different purposes. So let me break down which one should you use for querying and cleaning data. Querying Data: SQL is the best. reasons is that: Optimized for Databases – SQL is built specifically for querying structured data in relational databases (PostgreSQL, MySQL, BigQuery, etc.). Faster Queries – Databases are optimized for SQL, making it much faster than Python for filtering, aggregating, and joining tables. Simple Syntax – for example when one needs sales data from last month?

    Forging the Future: My Ten-Year Journey Growing with Rust
    Hello everyone, I am Zhang Handong(AlexZhang), an independent consultant and technical writer. I have been in the Rust community for ten years, and on the occasion of Rust's tenth anniversary, I want to write down my story. It may not be that extraordinary, but these ten years are where I come from today. Looking back on this journey, I see not just the evolution of a programming language, but the growth of a passionate community from nothing to something, from small to large. During these ten years, I experienced the transformation from a learner to an evangelist, and witnessed the entire process of Rust in China evolving from a niche language to gradual adoption by mainstream enterprises. This is a story about learning, sharing, challenges, and growth, and also a microcosm of Chinese dev…  ( 9 min )

    Angular: Quando os componentes precisavam de um módulo para chamar de lar
    Photo by Ryan Quintal on Unsplash Angular mudou e continua mudando... Antes, um componente precisava ser declarado dentro de um NgModule para "sobreviver". Agora, ele simplesmente existe — de forma autônoma. Sempre tive aquela analogia de que os componentes no Angular viviam dentro de caixas chamadas módulos, que por sua vez se encaixavam em outras caixas maiores, como o AppModule. No fim, tudo era uma grande construção de peças interconectadas, como um LEGO® bem estruturado. Mas tudo isso começou a mudar a partir da versão 14 do Angular, quando os chamados componentes autônomos (standalone) foram introduzidos como uma funcionalidade experimental. Na versão 15, essa abordagem foi estabilizada e passou a fazer parte oficial do ecossistema. E com isso vem mais uma linha de aprendizado, pois…  ( 4 min )

    Should you be vibe coding?
    After the recent post by DHH about “vibe coding”, I too felt the urge to take a plunge into the “vibe coding” pool as to what it is, and why it’s appealing. The term “vibe coding” was coined by Andrej Karpathy, who was also a founding member of OpenAI. As Karpathy describes, vibe coding is when you don’t think about code, you blindly trust whatever LLMs throws at you, and you vibe your way into building something. This approach to software development is made possible by how far language models have come (like Claude Sonnet), along with the rise of AI-powered editors such as Cursor and GitHub Copilot in VS Code. Vibe coding or not, coding with AI is quickly becoming the new default. Traditional software development has a steep entry barrier. You need to learn a programming language, grasp …  ( 4 min )

    Serverless Is a Lie (Unless You’re Using SQLite)
    We've twisted the word serverless into something vague. These days, serverless usually just means "I don't manage the infrastructure, someone else does." Which is fine. But it's also not the full picture. Because if we take the word literally (no server process to run, configure, or scale) then one database has quietly been the most serverless of all for over 20 years: SQLite. It doesn't run in the cloud. It doesn't need to connect to a remote API. It doesn't even require a boot-up process. It just works. And it's criminally underrated. Let's break this down into two flavors: This is the popular kind. You write your application and connect to a database that is fully managed by a third party. You don't worry about patching, scaling, or provisioning. Some examples: Firebase DynamoDB Neon Pl…  ( 5 min )
    The Quiet Crisis: How is AI Eroding Our Technical Competence?
    We are likely witnessing a quiet crisis in our technical teams. While we celebrate the productivity gains of AI tools, a more insidious process probably unfolds beneath - the surface—the systematic erosion of our fundamental technical capabilities. This is not pure speculation or technophobic fear-mongering; it is the reality playing out. The pattern is alarmingly consistent. A team adopts AI tools to enhance productivity. Initial results are impressive: faster code generation, quicker troubleshooting, more efficient documentation. Management celebrates the metrics. But something else is happening simultaneously—something few are measuring or even noticing until it's too late. Technical professionals are gradually losing their ability to think critically, solve novel problems, and understa…  ( 6 min )
    Implementing a Custom Reactive Library in Vanilla JS

    Async Is the New Superpower: Why Smart Developers Work Differently
    We all know the feeling. Suddenly your train of thought derails. You try to get back into flow, but it’s gone. Welcome to modern software development, where real productivity isn’t about working harder—it’s about working asynchronously. The Problem With Synchronous Everything Here’s the core issue: Synchronous communication assumes everyone is available at the same time. The difference is massive. If your team relies too heavily on live calls, pings, or "quick syncs," here’s what happens: Developers are constantly pulled from deep work Time zone mismatches create delays Pressure builds to be “always available” Creative thinking suffers due to fragmented focus As a developer, your job is to think clearly and build complex systems. That doesn’t happen in 15-minute chunks squeezed between Zoo…  ( 6 min )
    Log Aggregation with Python: Bringing Clarity to Distributed Security Data
    As your cybersecurity toolkit grows, one concept becomes increasingly important—aggregation. Logs from a single server tell a story, but when you start working with networks of devices, cloud services, containers, and multiple endpoints, you quickly realize that analyzing one log file at a time is not enough. You need a way to bring those logs together, sort through the noise, and create a unified view of what is happening across your environment. That is where log aggregation comes into play. By collecting and combining log data from multiple sources, you can detect patterns, respond faster to incidents, and make informed decisions. In this article, we will explore how to build simple but effective log aggregation workflows using Python, and why it is a powerful step forward in your secur…  ( 6 min )
    Set Up a MongoDB MCP Server in VS Code Like a Pro
    🚀 What is the Model Context Protocol (MCP)? The Model Context Protocol (MCP) is an open standard introduced by Anthropic that aims to simplify how AI applications—like chatbots, IDE assistants, or custom agents—connect with external tools, data sources, and systems. Before USB, connecting devices meant dealing with dozens of ports and drivers. Similarly, integrating M different AI apps with N different tools used to require M × N custom integrations—a huge development burden. MCP changes that to an M + N model: Tool creators only need to build 1 MCP server per tool App developers only need to build 1 MCP client per application 🧩 How it works MCP follows a client-server architecture: Hosts: AI applications the user interacts with (e.g., Claude, an IDE, a custom agent) Cli…  ( 4 min )

    The Cloud Resume Challenge: a perfect way to explore the cloud
    I came across The Cloud Resume Challenge by Forrest Brazeal while studying for my AWS CCP exam, and without much thought, I added the website to my bookmarks. I was certain that at some point, I would take on the challenge, as it seemed like a great opportunity to gain hands-on experience with AWS. And… I did — after passing my exam, I started working on the project. At the very beginning, I had to set up my AWS personal development environment to ensure that my account (and my wallet!) was properly protected. To do so, I decided to use AWS Organizations. I created a "root" AWS account and set up an AWS Organization with an Organizational Unit (OU) inside it. Under the OU, a new AWS account was created, and this was the account used to create any resources related to the project. At this s…  ( 5 min )

    Rethinking Front-End UX: Microsoft’s NLWeb and Natural Language Interfaces
    Web UX is having a moment. Not because of a new JavaScript framework (for once), but because of something much more fundamental: natural language as the interface itself. In early 2025, Microsoft introduced NLWeb, a project that brings conversational AI directly into websites via simple HTML attributes and JavaScript APIs. It's a shift that front-end developers and designers alike should be paying close attention to — because it fundamentally changes how users interact with the web. NLWeb is a Microsoft initiative designed to embed natural language interfaces directly into web experiences. Instead of rigid search bars or click-driven navigation, users can interact with a site using conversational queries — like asking a clothing store’s site, “Show me something under \$50 that's good for s…  ( 5 min )

    Practical Cases of Using the Singleton Pattern in Frontend Development
    The Singleton pattern is one of the most fundamental design patterns in software engineering, and it has several practical applications in frontend development. While often debated (as overuse can lead to issues), when applied judiciously, the Singleton pattern can solve specific problems elegantly in client-side applications. A Singleton is a design pattern that restricts a class to a single instance and provides global access to that instance. In JavaScript/TypeScript terms, it ensures that no matter how many times you try to create an instance of a class, you always get the same instance. Modern frontend frameworks often use Singleton-like patterns for state management: // Redux store (typically a Singleton) import { createStore } from 'redux'; import rootReducer from './reducers'; con…  ( 5 min )

Covered some variety: hash frequency, prefix sum tricks, and even a stack-based temperature-wait problem. Here’s the breakdown: Problem: Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]. For example, [0,1,2,4,5,6,7] might be rotated at pivot index 3 and become [4,5,6,7,0,1,2]. Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums.

    Do you know how it works? - Higher Order Functions (HOFs)
    TL;DR: Higher-Order Functions (HOFs) are functions that receive or return other functions. They’re key to functional programming, widely used in React, map(), filter(), and more. They help abstract repetitive logic, making your code cleaner, testable, and elegant. Classic examples: setTimeout, Array.map(), Array.filter(), function factories. Higher-Order Functions (HOFs), or First-Class Functions, became a hot topic in JavaScript over the last few years — largely thanks to functional programming principles and React. But despite the intimidating name, HOFs are actually pretty simple. They can be defined as: Functions that takes one (or more) functions as parameters, or Functions that return another function But what’s the point of passing a function as a parameter? Going deeper: why even p…  ( 7 min )
    Getting Started with AWS IAM: Managing Users, Groups, and Policies for Secure Access Control.
    AWS IAM (Identity and Access Management) is a service that helps you securely control access to your AWS resources.

    Will AI Replace Coders? How Developers Can Stay Relevant in the Age of AI Tools
    The software industry is undergoing a seismic shift. With the rise of AI tools for developers, we're not just changing how code is written—we're witnessing a transformation in who writes code, what skills are in demand, and how developers create value. For many in tech, it’s an exciting yet unsettling time. For years, programmers enjoyed high salaries thanks to a strong demand for software and a shortage of qualified talent. But that’s starting to change. Recent data reveals stagnating or declining salaries for entry-level and mid-level developers. At the same time, AI coding assistants like GitHub Copilot and ChatGPT are now capable of producing clean, functional code for increasingly complex tasks. This raises an urgent question: Will AI replace coders? The answer isn’t a simple yes or n…  ( 5 min )

    O que são Middlewares em APIs .NET?
    Se você já trabalhou com APIs em .NET, provavelmente já ouviu falar sobre Middlewares. Mas afinal, o que são e por que são tão importantes? Neste artigo, vamos explorar o conceito de Middlewares no contexto de APIs .NET, entender como eles funcionam e ver exemplos práticos de como utilizá-los. O que são Middlewares? Middlewares são componentes que formam o pipeline de processamento de requisições em uma aplicação .NET. Eles são responsáveis por lidar com solicitações HTTP (requests) e respostas HTTP (responses), permitindo executar lógicas antes e depois que uma requisição chegue ao seu endpoint final. Pense em um middleware como uma "camada" que a requisição passa antes de chegar ao seu destino (e também na volta, quando a resposta é enviada ao cliente). Analogia do Middleware Imagine um …  ( 5 min )
    Why I'm Building 12 Projects
    I completed General Assembly’s Web Developer Immersive in 2016. Back then, the curriculum focused on Vanilla JavaScript, jQuery, raw Ruby, Ruby on Rails, and the MEAN stack (MongoDB, Express, AngularJS, Node). At the time, everything moved at breakneck speed—and while we covered a lot, I don’t think the fundamentals ever had time to really sink in. What I did admire was the program’s emphasis on building and deploying projects. You were thrown into the deep end—forced to wrestle with unfamiliar concepts and figure things out as you built. Pre-LLM, that approach made sense. You just pushed through and got something working. Whether that led to long-term understanding, though, was a different story. It wasn’t until I enrolled in CSMC 203: Introduction to Programming at Montgomery College that things finally began to click. That foundational class helped me breeze through CSMC 206: Python Programming, and from there, everything felt more grounded. Eventually, I transferred to the University of Illinois Chicago to finish my CS degree. Being at a large public university, many professors rely on autograders to evaluate code. Imagine your first programming project being run through HackerRank or LeetCode-style tests without ever really being shown how to solve a problem. It’s easy to see how that could be discouraging—maybe even enough to push someone out of the field entirely. And UIC? They pile on the homework, especially in the engineering department. There isn’t much space to breathe, let alone learn deeply, until the semester ends. I’ve been balancing work and school for a while now, and I finally have the time and mental bandwidth to prove what I’m capable of—not as a cog in an assembly line, but as a developer who builds with intention. Over the coming months, I plan to build and share 12 projects that demonstrate why I’m a senior developer—and why I’m qualified for just about any role I apply to.  ( 3 min )

    SRP Demystified: Strengthening Authentication in the Digital Age
    In computer systems, username and password has become a widely used way to authenticate users. The evolution of password storage and authentication methods has gone through various stages to enhance security and protect user credentials. Here's an overview of the progression from plain text passwords to using Secure Remote Password (SRP) and the key concepts at each stage: Plain Text Passwords: In the early days of computing and network authentication, passwords were often stored in plain text on servers. This means that when a user entered their password, it was stored exactly as entered. The main problem with plain text storage is that if the server is compromised, attackers can easily obtain the passwords, potentially leading to unauthorized access to user accounts. Password Hashing: Th…  ( 5 min )
    Reconsidering DSA in Tech Hiring: A Builder’s Perspective
    Have you ever spent hours grinding LeetCode, only to wonder: Is this what software engineering is really about? Data structures and algorithms (DSA) dominate tech hiring, especially at big tech companies. They’re a measurable way to test coding skills, logic, and problem-solving under pressure. But as someone who’s been through the DSA gauntlet and come out the other side, I’m starting to question: Are we filtering for the right kind of talent? DSA isn’t the enemy—it’s a useful tool. But when it becomes the only lens for evaluating engineers, we risk missing out on builders, pragmatists, and innovators who don’t shine in 90-minute coding puzzles. Let’s rethink how we hire and what we’re optimizing for. My Journey: From LeetCode to Real Systems I’ll be honest: I’ve played the DSA game. I’ve…  ( 5 min )

    I've created a text-to-form builder - feedback appreciated
    For several years form-data.com offered a forms-backend as a service, for people building their own static forms. Creating a form builder was an idea that I played with for a long time. However, as a developer I didn’t like most of the form builders out there. It always feels like I have to fill-in a (really complicated) form just to create a form. What I ended up with was a text-to-form builder. On the left you write simple text descriptor, and on the right you get a form. And of course, as with any product these days, you can just ask the AI to write it for you. Publish the form is simple, and you’ve got yourself a hosted form. And the backend gets all you’d expect from a forms the backend, including spam filter, email notifications, auto-response emails and integrations. I’d really appreciate if you give it a go and share any feedback - the studio is open without registration, and if you want to publish you need to signup without credit-card, and you get 100 free credits.

Static websites are the most basic type of web application. They consist of HTML, CSS, and JavaScript files that are pre-rendered and served directly to the user's browser. This means that every page on the website is a separate file, and eac…  ( 6 min )
    How I’m Learning AWS as a Beginner: What Finally Made Networking Click
    Starting my cloud computing journey with AWS Cloud Practitioner, I honestly struggled to grasp some of the concepts. Networking, IPs, even the general cloud terms, all felt new and overwhelming. Despite the struggles, I had already set a purpose: to understand why things work the way they do, not just memorize terms. So I started digging deeper apart from the AWS student guide, I watched YouTube explainers, reading more AWS docs, and learning from how experts on LinkedIn approach problems. One thing that helped a lot was reading how cloud professionals think about business needs of their clients, and how they approach AWS tools and services to solve them efficiently. Learning by Research & Reasoning CIDR and IP ranges Subnets and routing Internet Gateways and NAT Gateways I watched experts like NetworkChuck on youtube explaining how these connect in real cloud architectures, and attended a few expert sessions(like the ones from ALX) to build deeper understanding. I also documented everything on Notion, using toggles to organize concepts clearly and link them to real examples. Writing things out helped me make sense of abstract topics. Hands-On: Bringing It All Together After building that foundational understanding, I went hands-on with the AWS Console and practiced: Launching EC2 instances (choosing AMIs, instance types, configuring VPCs/subnets) Setting up IAM roles and using User Data scripts for automation Using key pairs and Git Bash to SSH into my instance Ran this command to verify the system: Got this output: 5.10.236-227.928.amzn2.x86_64 Amazon Linux 2 I explored basic Linux commands, storage configs, and how tagging and security groups improve structure and access. Progress Over Perfection I’m Curious… If you’ve walked the AWS learning path, what was your turning point? Was there a concept that “clicked” and made the rest easier?

We’ll use the same California Housing dataset so you can reuse your environment and immediately see the effects of each technique. When sensors drop packets or humans skip survey fields, you get NaN (Not‑a‑Number) entries. Most scikit‑learn models will straight‑up error if you feed them NaNs, so we MUST decide what to do. The three classic moves are: Strategy What it does When it’s OK Drop Columns Delete any column containing any NaNs Column is mostly NaNs or not predictive Imputation Replace NaNs with a statistic (mean/median) Numeric columns with moderate sparsity Extended Imputation Impute and add a boolean “was_missing” flag When the fact a value is missin…  ( 6 min )
    The Problem with Web Components
    The real problem with Web Components is simple: There is no clearly defined road to success for using them. No singular go-to guide. Up until recently the standard has been in flux. And in some ways, still is. But the core APIs have stabilized, and many developers are jumping into the scene. However, it can be hard for someone who hasn't followed the evolution of this standard to know where to begin. Learning the concepts necessary to use this powerful set of tools is a challenge. Many articles exist on this subject, but the real useful information is scattered, buried among outdated tutorials demonstrating experimental features that have changed over the years. So, if you have been wondering how to get to started crafting your own components from scratch, you are reading the right article…  ( 8 min )

    Detecting and Fixing Vulnerabilities in Code Suggested by Cursor and Windsurf
    AI-powered code suggestions from tools like Cursor and Windsurf can introduce security flaws for several reasons. First, these models are built on extensive datasets that include publicly available code and third-party libraries, many of which already contain known weaknesses. As a result, the AI may inadvertently learn and replicate those insecure patterns. Additionally, these tools often produce predictable and repetitive code structures that, while syntactically correct, may be vulnerable to exploitation if not verified properly. Another key concern is their limited understanding of the broader application environment, including specific business logic or security policies, leading to code suggestions that may function correctly but pose risks when deployed. The fast-paced nature of A…  ( 4 min )

    From JavaScript to Python: A Syntax Guide for Developers
    Introduction If you’re a JavaScript developer diving into Python, you’ll find many concepts familiar but with syntactic twists. Python’s emphasis on readability and simplicity means fewer brackets, strict indentation, and a different approach to common tasks. Let’s break down key differences with side-by-side examples. 1. Variables and Constants JavaScript let mutableVar = 10; // Mutable const immutableVar = 20; // Immutable Python mutable_var = 10 # No 'let' or 'const'—all variables are mutable IMMUTABLE_VAR = 20 # Convention: UPPER_CASE for "constants" (not enforced) Key Notes: Python uses snake_case (not camelCase). No var or const—just assign values. 2. Data Types JavaScript Python Notes number int, float Python distinguis…  ( 5 min )

    Artisan Commands You're Not Using (But Definitely Should)
    If you’ve worked with Laravel, you’ve typed php artisan serve php artisan migrate. And while those are useful, they barely scratch the surface of what Artisan can do. Artisan isn’t just a tool for running migrations or spinning up servers—it’s a command-line companion that can boost your productivity, simplify debugging, and teach you more about Laravel’s inner workings. Yet many developers (my past self included) tend to stick with the same 3-4 commands and miss out on some seriously powerful features. Whether you’re just starting with Laravel or you’ve been building apps for years, it’s worth revisiting Artisan with fresh eyes. In this post, I’m diving into some of the lesser-known, underrated, or just plain useful Artisan commands I think every Laravel developer should explore. php art…  ( 5 min )
    In-depth details of Class in JavaScript
    A class in JavaScript is a blueprint for creating objects. It allows you to define reusable object structures with properties and methods, making object creation and management more structured and efficient. JavaScript classes are a blueprint for creating objects. They introduce object-oriented programming (OOP) concepts like encapsulation, inheritance, and abstraction. Before ES6, JavaScript used constructor functions and prototypes to create and manage objects. With ES6, class syntax was introduced to provide a cleaner, more intuitive way to define object templates. JavaScript allows creating objects without classes using object literals, but classes provide advantages in scalability, maintainability, and reusability. Let's explore: class Person { constructor(name, age) { this.name…  ( 11 min )

    ✨ Understanding `AND (&&)` and `OR (||)` Operators in JavaScript
    Hello friends 👋 In this blog, I will explain two simple and powerful tools in JavaScript: the AND (&&) and OR (||) operators. These are called logical operators and are used to check conditions. Let’s understand them with examples that relate to real life 🚶‍♂️🍕💻 AND (&&)? The && operator checks if both conditions are true ✅✅ If both are true → result is true If any one is false → result is false ❌ Let’s say you want to go for a walk 🚶‍♀️ You will go only if: ➡️ It is not raining ☀️ AND ➡️ You have free time 🕒 let isNotRaining = true; let hasFreeTime = true; if (isNotRaining && hasFreeTime) { console.log("You can go for a walk! 🚶‍♂️"); } else { console.log("Stay at home! 🏡"); } 📌 If both conditions are true, the walk will happen 📌 If even one is false, no walk today! OR (||)? The || operator checks if at least one condition is true ✅ If one is true → result is true If both are false → result is false ❌❌ You will order food 🍔 if: ➡️ You are hungry 😋 OR ➡️ There is no food at home 🍳 let isHungry = false; let noFoodAtHome = true; if (isHungry || noFoodAtHome) { console.log("Order food online! 🛵"); } else { console.log("No need to order food. Eat at home! 🍽️"); } 📌 Only one condition needs to be true to order food ➡️ && → Both conditions must be true ✅ AND ✅ ➡️ || → Only one condition needs to be true ✅ OR ❌ let hasLaptop = true; let hasInternet = false; // Check if you can work from home if (hasLaptop && hasInternet) { console.log("You can work from home 💻🏠"); } else { console.log("You can't work from home 😕"); } // Check if you can still do something useful if (hasLaptop || hasInternet) { console.log("You can still be productive! 💡"); } Operator Result is true if... AND Both conditions are true ✅✅ OR At least one condition is true ✅ or ✅ I hope this blog helps you understand AND and OR operators in a fun and easy way! 😊 These are very helpful when writing conditions in JavaScript.

    What is Backend Development Architecture?
    Backend development architecture refers to the structural design and organization of the server-side components of a software application. It focuses on how the backend handles data processing, business logic, database interactions, authentication, API integrations, and server management to ensure scalability, security, and high performance. Modern backend architecture often leverages microservices, cloud-native infrastructure, containerization (like Docker and Kubernetes), RESTful and GraphQL APIs, and event-driven systems. Key trending concepts include serverless computing, API-first design, database optimization with NoSQL or NewSQL, and real-time data processing. This architecture plays a crucial role in building robust, maintainable, and scalable web and mobile applications that can handle complex user demands and evolving digital ecosystems.  ( 3 min )

    AI Engineering: The Meme, the Madness, the Motivation
    When Curiosity Strikes It always starts cute. You’re scrolling through LinkedIn, hear “AI is the future,” and suddenly your inner coder whispers: “Yeah, I’ll become an AI Engineer.” You open a YouTube tutorial, start learning Python, maybe dabble in a little scikit-learn... and for a moment, you feel invincible. Then Reality Hits Boom — you meet: Gradient Descent (why does it feel like I'm the one descending?) Backpropagation (stabbed in the back... with math) “CUDA not detected” (even though your GPU is flexing in Task Manager) Transformers (not the Optimus Prime kind ) Your innocent coding dreams become haunted by tensors and traceback errors. The Dev Setup, but Make it Chaotic You build your workstation: Dual monitors Fancy keyboard RGB lights Motivation? Fading... Mentally? Still in a baby playpen.

    Security is a Mess – How Plang Helps Fix It
    This post dives into Plang, an intent-based programming language that interprets natural language. For more, visit plang.is or get started here. Security is hard. As developers, we’re not exactly great at it. The issue is that security is binary - it either works 100% or it doesn’t at all. If there’s a flaw in your code, an attacker could gain full access to your system. Worse, you can never truly prove that something is 100% secure. All you can do is try to prevent every possible way in, which requires a lot of experience and a lot of eyes on the code. The only thing that gets you closer to 100% is time and scrutiny. That’s the key to secure code: experienced developers looking at it, lots of them, and enough time passing without a breach. We never know it’s secure. We can only hope. If I…  ( 5 min )

    I Took the Long Way Home to Code, and That’s Okay
    Hi, I'm Choice 👋🏽 I’m a Ruby on Rails developer with a background in chemistry — but really, I’m someone who’s rebuilding life from the inside out. My journey into tech wasn't linear. Like many Nigerians, I studied something safe (Chemistry), even though I’d always loved computers. Life happened, and I took detours that forced me to pause, reflect, and reimagine everything. Coding became more than a skill; it became a language of healing, structure, and hope. Since transitioning, I’ve built full-stack apps like ShopMe (e-commerce), DevConnect (developer community), and I’m currently working on TextMe, a real-time chat app. I’ve used tools like: Ruby on Rails (8), SolidQueue for background jobs AWS S3 for image storage React, Firebase, TailwindCSS, Bootstrap I’m also learning Django and Next.js 🌱 But beyond the tech, I’m creating soulful, user-centered projects — the kind that feel like quiet spaces on the internet. My content brand DearChoice is where I share faith, healing, and growth. My passion project Yardly aims to help communities in Nigeria discover local talents and preserve culture — online. I want to connect with devs who are learning with heart. Who are figuring things out slowly. Who care about the why, not just the how. If that sounds like you, let’s chat 🤝 Let’s build, share, reflect — and grow better together. ✨ 🧩 You can check out my projects on GitHub @ChoiceG 💼 And find me on LinkedIn See you around! – Choice 🌿  ( 3 min )
    Not Another UI Test: How API-First Testing Saved Our Pipeline
    If you've ever pushed a hotfix on Friday, only to get a bug report five minutes later… You know the pain of mobile testing. Between flaky UI tests, emulator delays, and device-specific weirdness, testing often feels like guesswork. We wanted something cleaner and found that API-driven mobile testing changes the game. Emulators that crash at the worst times Tests that pass locally but fail in CI Writing brittle UI test scripts that break on every UI tweak Hours wasted waiting for device builds to finish Sound familiar? We figured there had to be a better way - and there is. Instead of relying solely on UI flows, we started triggering mobile app behavior via APIs during CI runs. This gave us: More control over test execution The ability to skip the UI when not needed True automation across devices, even without a UI Turns out, you don’t need to “see” the app to know it’s working - you just need to test the right paths, fast. We integrated a lightweight API testing layer into our existing pipeline. We used a tool that let us: Run tests on real devices, remotely Trigger workflows from GitHub Actions Receive results via webhook Skip maintaining emulator scripts It plugged into our pipeline almost effortlessly, and we never looked back. Less flakiness Faster feedback Works across device types Easy to scale Most importantly, it lets us move fast without breaking things. We tried a few things, but ended up using tools like NativeBridge(the cheapest), Appetize, BrowserStack, and Lambda that made the API integration part smooth. No SDK installs, no heavy setup — just clean test runs triggered by API. We didn’t plan to switch our whole testing strategy, but it kind of happened naturally once we saw how stable and scalable it felt. You don’t need to rewrite your entire testing suite. Just look for places where API-driven checks can replace manual ones — and start small. It’s not about being trendy — it’s about not burning out your dev team maintaining flaky test code.  ( 4 min )
    Understanding CSS Transforms – A Beginner's Guide
    Today, I learned about CSS Transforms, and I’m excited to share what I discovered! The transform property in CSS lets you visually manipulate elements — you can move, rotate, scale, and skew them without changing the actual layout. It's super useful for animations, hover effects, and modern UI design. Here are some common 2D transform functions: translate(x, y) Moves an element from its original position. transform: translate(50px, 100px); rotate(angle) Rotates an element clockwise. transform: rotate(45deg); scale(x, y) Scales an element in the X and Y directions. transform: scale(1.5, 1.5); skew(x-angle, y-angle) Skews the element. transform: skew(20deg, 10deg); 3D transforms add depth to your elements and make them appear to move in 3D space. To view them properly, you often need to use the perspective property on the parent container. rotateX(angle) Rotates the element around the X-axis. transform: rotateX(45deg); rotateY(angle) Rotates the element around the Y-axis. transform: rotateY(45deg); rotateZ(angle) Rotates the element around the Z-axis (similar to 2D rotate). transform: rotateZ(45deg); translateZ(distance) Moves the element closer or farther away in 3D space. transform: translateZ(50px); perspective(n) Defines the distance between the viewer and the 3D element. .parent { perspective: 500px; } .box { width: 100px; height: 100px; background: teal; transition: transform 0.3s; } .box:hover { transform: scale(1.2) rotate(10deg); } When you hover over the box, it grows and rotates — all thanks to the transform property! CSS transforms (2D and 3D) are powerful tools that add creativity and interaction to your web designs. I enjoyed experimenting with different effects and seeing how elements can move and rotate on screen. Next, I’m planning to learn about CSS animations and how they work with transforms.  ( 4 min )

    Cartouche — a social network where you're the only human
    Hello everyone 👋 I’ve recently started building a personal open source project called Cartouche. It’s a one-user social network simulator. You write posts like on Twitter, and get reactions from hundreds (or thousands) of AI bots — each with memory, personality, and their own behavior. The idea Cartouche is a place to express yourself freely — without the pressure of real audiences. You get thoughtful replies, memes, debates, praise, skepticism, and support… but all of it from simulated users with their own quirks and styles. They react over time, not instantly. Some follow you, others unfollow. Some remember what you said weeks ago. Some adore you. Some argue. Some just drop a meme and vanish. It’s a space for testing ideas, exploring identity, or just yelling into a virtual crowd that somehow yells back — in meaningful, sometimes surprising ways. Why? Because sometimes you want feedback — but not from real people. What's built so far? A small piece of the frontend (React + Vite) A mobile-first UI (with live demo): View Demo Figma design (mobile): View on Figma GitHub repo: Cartouche on GitHub Full project overview (Gist): Read here Tech stack (planned) Frontend: React + Vite (hosted via Nginx in Docker) Backend: Python (likely FastAPI) Storage: MinIO for media Database: MySQL, maybe Redis AI: Google Gemini API (or user’s choice) Deployment: All via Docker Compose, one-command setup Looking for like-minded folks I’m building this solo for now. It’s a pet project — no deadlines, no pressure, no money involved. Just a place to build something interesting and fun. If this concept resonates with you and you'd like to contribute — whether with code, ideas, or questions — feel free to reach out. Happy to chat. Thanks for reading. — @metimol  ( 3 min )

    How Weaving Looms Led to Today’s Computers: A Simple History
    Have you ever thought about how the simple act of weaving cloth is connected to the computers we use today? It might sound surprising, but the story of computers begins with weaving looms! Long ago, people used looms to weave fabric. These looms created patterns by controlling how threads crossed each other. In the early 1800s, a clever inventor named Joseph-Marie Jacquard invented a loom that used punched cards to tell the machine which pattern to weave. These cards acted like instructions — telling the loom what to do step by step. This was one of the first examples of a programmable machine — a machine that could follow a set of instructions automatically. Around the same time, inventors were building machines to help with calculations. People like Blaise Pascal and Gottfried Wilhelm Le…  ( 4 min )

    Fast API Request Handling
    In FastAPI, how route handlers (endpoints) behave in terms of parallelism and concurrency depends on whether they are defined using async def or def, and whether the work inside them is I/O-bound or CPU-bound. Here are the four combinations of route handlers and how they affect parallel or concurrent handling of requests: async def with async I/O-bound work (e.g., await asyncio.sleep, database calls) @router.get("/async-io") async def async_io_route(): await asyncio.sleep(2) return {"status": "async io"} Handled concurrently Non-blocking — multiple such requests can be handled at the same time. Best performance for I/O tasks like DB queries, network calls, file access. async def with CPU-bound work (e.g., heavy computation, no await) @router.get("/async-cpu") async def …  ( 4 min )

    AWS Alert Validation - Lambda
    We are continuing the blog series about testing your AWS alarms. The first part of the series, which looked at CloudWatch actions and EC2 alarms, can be found here. An untested alarm is not one you can trust. This time we will look at alarms for your Lambda functions. As before, we will test the alarms by ”breaking” the Lambda so you get the same outcome as when a real issue would occur. Since this is Lambda, we will add code (or entire Lambdas) to make the Lambda act as we want. I will use Python, but the logic works for all the other supported languages. I have an examples repo where you can find Terraform code to deploy Lambas and required resources to AWS to test the alarms. You will need to connect your alarms to the Lambda functions, though. Remember to lower the thresholds on your a…  ( 6 min )
    Building a Self-hosted IAM Platform to Add SSO to My Home Lab
    A growing problem with my home lab is password fatigue. Each time I add a new service to my network, I generate a new random password for it. I got by initially with using a different password for every service by storing them in a password manager, but as the number of services exceeded double digits, having to open my password manager every time I want to access each service is starting to hinder my productivity. I needed a self-hosted SSO solution for my home lab services, so I deployed an open-source IAM platform that supports SSO via OIDC, OAuth, and LDAP protocols to my Kubernetes cluster. The initial design was simple. I only needed SSO for my services, namely Grafana and Syncthing, and my solution must support both modern protocols like OAuth/OIDC and legacy protocols like LDAP.

    Which Compression Saves the Most Storage $? (gzip, Snappy, LZ4, zstd)
    Compression setting are set and forget in most cases, if it works no reason to change it.

I covered most of the algorithms discussed in this post previously in Compression Algorithms You Probably Inherited, where I summarized the info I collected while researching. But I wanted to sanity-check the findings myself and decided to run some benchmarks. This should help me see if compression actually makes a difference for storage costs. To keep things real, I used actual data: NYC TLC trip records. Each month’s data file was ~500MB. I combined a few to get files at 500MB, 1.6GB, 3.9GB, and 6.6GB.

    6 Best Open-Source Ticketing Systems for 2025
    Originally published at https://www.nocobase.com/en/blog/open-source-ticketing-systems. Last year, as the number of NocoBase users grew, we faced a pressing challenge: how to efficiently manage customer feedback and support requests. Users reached out via emails, community forums, and even through internal colleagues. With information scattered across multiple channels, issues were easily missed, and collaboration on follow-ups became cumbersome. We realized it was time to implement a ticketing system tailored to our workflows. So, we decided to build our own custom ticketing system using NocoBase.

    Schemas in PostgreSQL: A Practical Guide for Developers
    Schemas in PostgreSQL aren’t just for large systems—they’re for anyone who wants to keep their data structured. A schema is like a folder within your database where related objects (tables, views, etc.) are grouped together. This helps you separate concerns, organize logic, and secure your data more effectively. Here’s a practical look at how they work. Organization: Separate business domains (like inventory and users). Control: Limit access to different parts of your app. Maintenance: Make backups and updates more targeted. Cleaner Queries: Avoid clutter in your namespace. Comes with every PostgreSQL database. If you don’t specify a schema, objects go here. Created manually to isolate logic or control access. CREATE SCHEMA hr; How Data is Structured PostgreSQL Cluster └── Database └── Schema └── Tables, Views, Functions, etc. This layered model helps manage growing projects without chaos. CREATE SCHEMA inventory; CREATE TABLE inventory.products ( product_id serial PRIMARY KEY, product_name VARCHAR(255), price DECIMAL, stock_quantity INT ); CREATE TABLE public.users ( user_id serial PRIMARY KEY, username TEXT, email TEXT ); Using schemas lets you organize your app by responsibility—making it easier to evolve or scale parts of your system. Yes, and it’s a common best practice. Public is open by default; custom is restricted unless granted. Not directly, but they help manage large systems more cleanly. Yes, using tools like pg_dump or schema migration scripts. PostgreSQL schemas give you better structure, access control, and scalability. They're an essential tool for organizing your data without complicating your architecture. For a more detailed guide, visit the schemas in PostgreSQL article.  ( 17 min )

    Docker Like a Pro: Essential Commands and Tips
    Docker has revolutionized the way developers build, ship, and run applications. Whether you're a beginner or an experienced developer, mastering these essential Docker commands and tips will make you more efficient and productive. Before using Docker, ensure you have it installed by running: docker --version To get detailed system info, use: docker info Quickly run a container with: docker run -d -p 8080:80 --name my-container nginx This runs an Nginx server in detached mode (-d), mapping port 8080 on your machine to port 80 inside the container. To see all running containers: docker ps To include stopped containers: docker ps -a Stop a running container: docker stop my-container Remove a stopped container: docker rm my-container Remove all stopped containers at once: docker rm $(docker ps -aq) Over time, unused images take up space. Remove them with: docker image prune -a If you have a Dockerfile, build an image with: docker build -t my-app . This tags the image as my-app. Use interactive mode to execute commands inside a running container: docker exec -it my-container /bin/sh For Ubuntu-based containers, use /bin/bash. Monitor logs with: docker logs -f my-container The -f flag shows real-time updates. Copy files from your local machine to a running container: docker cp myfile.txt my-container:/app/ Copy files from a container to your machine: docker cp my-container:/app/myfile.txt . Instead of running multiple containers manually, define them in docker-compose.yml and start them with: docker-compose up -d Stop and remove all services: docker-compose down 💼 LinkedIn | 📂 GitHub | ✍️ Dev.to | 🌐 Hashnode Found this useful?

Animations have quietly become one of the most influential parts of the user experience. They’re no longer just about making things "look cool"—they guide the user, provide feedback, and elevate interaction into engagement.

I went into panic mode. I applied to many companies. Anything with the word "coding" or "software engineering" in the job description. I even applied to a FAANG though I rejected that idea years ago. But I just got radio silence. I know because I wasn't the only one going through layoffs. The entire industry was. I even talked to an ex-coworker and he told me he had sent one hundred applications.

    Do You Use SELECT * or Explicit Columns in Production Queries?
    SQL gives us the handy SELECT * to quickly grab all columns from a table but should we really use it in production? Some developers love the speed and convenience of SELECT *, especially during prototyping or when working with wide tables. Others argue it leads to performance issues, tight coupling, and unreadable queries and insist on selecting only the columns you actually need. Do you prefer SELECT * or writing explicit column names in your queries? Have you ever run into a real world issue because of SELECT *? What do you think is the best practice, and why?  ( 3 min )

    Understanding TypeScript: Inference, Types, and Generics
    Type Inference TypeScript can often guess types automatically. This is called type inference. When you assign a value without an explicit type, TypeScript infers it. For example: let count = 10; // inferred as number let message = "Hello"; // inferred as string The compiler knows count is a number and message is a string from these initial values. Type inference helps keep code concise and still type-safe. You don't always need to write : number or : string because TypeScript figures it out. Less code: You skip repetitive type annotations. Safety: Even with fewer annotations, TypeScript checks types. Readability: Code stays clean while avoiding obvious errors. However, you can still add type annotations if it makes the code clearer or if a variable’s type isn’t obvious. …  ( 6 min )

    DOJ is investigating Coinbase data breach— Report
    The US Department of Justice is reportedly conducting a probe over Coinbase’s contracted customer service agents in India, who accepted bribes in exchange for allowing criminals access to user data. According to a May 19 Bloomberg report, DOJ investigators are looking into the data breach, which Coinbase disclosed to the public on May 15. The exchange reported that a group of customer support contractors — subsequently fired — “abused their access to [...] systems to steal the account data for a small subset of customers.” “We have notified and are working with the DOJ and other US and international law enforcement agencies and welcome law enforcement’s pursuit of criminal charges against these bad actors,” said Coinbase’s chief legal officer, Paul Grewal, according to Bloomberg. Related: New Zealand man arrested in $265M crypto scam tied to FBI probe Though “no passwords, private keys, or funds were exposed” according to Coinbase, the data breach resulted in social engineering attacks targeting users, including a Sequoia Capital partner, with losses estimated at up to $400 million. The attackers also attempted to extort $20 million from Coinbase in exchange for not disclosing the breach, which the company refused. Backlash in the courts The attempted social engineering attacks have resulted in Coinbase users filing several lawsuits against the exchange, alleging that the company mishandled their personal data. One user, a retired artist named Ed Suman, reported losing $2 million to the scammers.

    What to expect at Trump’s memecoin dinner
    On May 22, US President Donald Trump is expected to host up to 220 people who had purchased the most significant quantities of his memecoin at a private event in Washington, DC. Though the exact number of attendees was unknown as of May 19, reports and blockchain data have revealed some of the tokenholders who qualified to apply for the May 22 dinner and “VIP tour” and reception, presumed to be in the White House.

    Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report
    Circle, the issuer of stablecoin USDC (USDC), is still planning an initial public offering (IPO), but the company is also in informal talks with Ripple and Coinbase about a sale, according to a report from Fortune. Circle is seeking at least $5 billion, which is its target for the IPO, according to the four banking and private equity sources Fortune cited. Ripple tried to purchase Circle on April 30, but the $4 billion to $5 billion bid was rejected as being too low. If Ripple or Coinbase were to buy Circle, the details of a purchase would differ. Ripple would pay using cash and XRP (XRP), a cryptocurrency that Ripple created. Coinbase, on the other hand, would use cash and stock. Coinbase and Circle have a relationship dating to 2018, when they launched the Centre Consortium. That ventur…
    Bitcoin futures data aligns with BTC traders’ hope for new all-time highs
    Key takeaways: Bitcoin buying in the spot and futures markets helped BTC price keep its upward momentum despite $170 million in margin liquidations. Weak stablecoin demand in China and the limited use of futures leverage suggest Bitcoin’s current rally is sustainable. Bitcoin (BTC) price has displayed strength at the $102,000 support level on May 19, following the $170 million in liquidations of leveraged positions. The abrupt $5,000 correction after hitting $107,090 may have been unexpected, but it does not mean the odds of reaching an all-time high in the near term are lower, especially since Bitcoin derivatives metrics have shown resilience.

In prepared remarks for a May 19 speech, Atkins said it was a “new day” for the crypto industry under the current leadership of the SEC.

    ‘Before Bitcoin, my most successful investment was shorting the Bolivar’ — Ledn co-founder
    Before discovering Bitcoin (BTC), Ledn co-founder Mauricio di Bartolomeo found success shorting the Venezuelan Bolivar as it rapidly lost value against the stronger US dollar. Now, with the US dollar depreciating against Bitcoin, borrowing against Bitcoin instead of selling it has become a more viable strategy. “Prior to Bitcoin, my most successful investment was shorting the Bolivar with dollars,” di Bartolomeo told Cointelegraph in an exclusive interview at the Consensus conference in Toronto, Canada.  “I was borrowing Bolivars and buying dollars with them, holding the hard dollars and having a borrow [position] on the weaker currency,” he said. The arrival of Bitcoin-backed loans means investors can now effectively implement the same strategy by using a harder currency as collateral.  L…

    Community sales are the future of crypto fundraising
    Opinion by: Darius Moukhtarzadeh, Research Strategist at 21Shares A new wave of crypto fundraising is emerging, changing how Web3 projects launch and who can invest at an early stage: Community Sales. At first glance, community sales may seem reminiscent of the ICO (Initial Coin Offering) era from 2016–2017. Yet, they represent a significant evolution that better aligns with crypto's core values of democratization, transparency, and inclusivity. Projects should include community sales as a core element of their fundraising strategy, besides raising from angel investors and VCs.

    Australian court ruling could lead to $640M in Bitcoin tax refunds
    A court decision in Australia could open the door to as much as $640 million in capital gains tax (CGT) refunds on Bitcoin transactions after a judge ruled that crypto should be treated as money rather than a taxable asset.  On May 19, the Australian Financial Review (AFR) reported that the decision arose within a criminal case involving federal police officer William Wheatley, who allegedly stole 81.6 Bitcoin (BTC) in 2019. At the time, the assets were worth roughly $492,000. At current market prices, the tokens are valued at more than $13 million.

    Vitalik Buterin proposes partially stateless nodes for Ethereum scaling
    Ethereum co-founder Vitalik Buterin unveiled a proposal to preserve trustless, censorship-resistant access to Ethereum, even as the network scales.  On May 19, Buterin shared a post outlining how to make Ethereum’s layer-1 scaling “more friendly” to users running local nodes for personal use. The Ethereum co-founder highlighted the importance of independent users running nodes, saying that a market dominated by a few Remote Procedure Call (RPC) providers risks censorship.  RPC providers let wallets, users and apps interact with the blockchain without running their own nodes.

Buterin said there are risks to this setup.  “A market structure dominated by a few RPC providers is one that will face strong pressure to depl…

    ‘Sats’ vs ‘bits’ debate reignites amid proposal to change Bitcoin base unit
    A recent proposal that aims to change Bitcoin’s base unit to make it easier to understand as a payment tool has run into opposition, with critics saying Bitcoin’s satoshis are no more confusing than the dollar’s cents.

It follows a 2017 proposal from Bitcoin developer Jimmy Song to create “bits,” representing one-millionth of 1 Bitcoin.

    How to Convert EPS to PNG: A Developer’s Guide
    EPS vs PNG: What’s the Difference? EPS (Encapsulated PostScript) is a vector file format used mainly for print workflows and high-quality graphics. It retains shape, curve, and scaling data—great for logos and illustrations. PNG (Portable Network Graphics) is a raster format ideal for digital content. It supports transparency and lossless compression, making it perfect for websites, apps, and UIs. So why convert? Because: Browsers don’t support EPS natively PNG is lighter and easier to preview You might need thumbnails or web-friendly versions of design assets Python makes this easy using the wand library (a wrapper for ImageMagick): bash with Image(filename='logo.eps', resolution=300) as img: ImageMagick is a powerful command-line tool that supports EPS to PNG conversion out of the box: bash bash If you're building a web app or serverless function and don’t want to install heavy dependencies, consider these APIs: Cloudinary: Offers format transformation pipelines CloudConvert: Easy-to-use REST API ConvertAPI: Handles over 200 file types including EPS Here’s a sample request using CloudConvert: bash https://api.cloudconvert.com/v2/jobs \ Web apps that allow users to upload and preview logos or designs Automated pipelines for asset generation or optimization CMS tools that generate thumbnails or social previews from design files Whether you're writing a backend service or automating a design workflow, converting EPS to PNG is a straightforward but essential task. For local scripts, go with Python or ImageMagick. For cloud scalability, plug into an API. Got a preferred method or tip for EPS to PNG? Drop it in the comments or share it on GitHub.  ( 4 min )
    Beyond Promises
    Automation promises simplicity—tasks repeated flawlessly, outcomes consistently predictable, and infrastructure harmoniously stable. At the heart of these captivating promises lies idempotency , an elegant idea proclaiming that no matter how many times we run an operation, the result remains steadfastly unchanged. Yet, the shimmering promise of automation's reliability seldom matches reality. In the messy arenas of operational infrastructure, idempotency frequently escapes our grasp. Like a distant horizon, it coaxes and compels—but rarely feels fully attained. Why does the concept of reliable idempotency struggle when translated from whiteboards to production realities? The culprit is the capricious, ever-changing landscape of real-world infrastructure management. Consider a familiar scen…  ( 6 min )

    Building a MIPS Emulator (Part 1): Loading and Reading Raw Binary
    "I didn’t know how anything would work when I started—just had a vague sense I’d figure it out along the way." I wanted to understand how computers really work—beyond just writing high-level code. I needed to deepen my knowledge and prove to myself that these low-level systems aren’t inherently difficult; you just need the right concepts. So, I decided to build a MIPS emulator. I broke it down into three parts: Loading the binary code from a MIPS program Decoding the binary instructions Executing them At first, I didn’t even know how to load a file, let alone parse instructions. So that’s where I began. We need a binary file that contains MIPS instructions in raw binary format. There are other formats like ELF, but I chose to keep it simple with a .bin file.

    What If Your Process Management Is Quietly Killing Your Productivity?
    Introduction: The BPM Paradox Business Process Management (BPM) is designed to improve efficiency, streamline operations, and boost performance. In theory, it helps automate workflows, align teams, and bring structure to everyday tasks. But in reality, many companies are still using outdated, rigid, and overly complex BPM systems. They believe they’re becoming more efficient… when in fact, they’re silently slowing themselves down. What if your BPM system—designed to drive performance—is actually blocking innovation and costing you time?

It involves defining every step in a process (e.g., invoice approvals, onboarding, leave requests), and turning th…  ( 5 min )

    Why you should become a developer marketer (A cold invitation)
    Back then, there was just digital marketing. Then product marketing. We’d segment audiences, figure out what they need, fear, and want. We’d find where our product fits, then build campaigns to fish. Developer marketing isn’t so different. Except, once you identify this audience, you don’t fish. You sit with them. You learn their pain points. You plug into their workflow. You speak their language. And you earn the one thing that moves the needle: trust. I’ve written a lot about developer marketing. Most of it lives on The New Stack and Hackmamba. But I noticed something. Nearly every piece out there speaks to companies. They explain why developer marketing is worth investing in or how to structure a better strategy. Even the best ones focus on frameworks, not the people stepping into this …  ( 11 min )

    Migrando koa-graphql para grahpql-http
    Recentemente eu desenvolvi o desafio da Woovi com Koa.js e GraphQL (link do projeto). Uma das especificações opcionais era o uso do graphql-http, substituto do koa-graphql, que está presente no playground disponibilizado. No entanto, me deparei com alguns problemas iniciais: diversas funcionalidades não estavam presentes no graphql-http, visto que ele é apenas uma implementação do GraphQL sobre HTTP, isto é, é simples e minimalista. Primeiro, por quê? Bom, principalmente, porque koa-graphql foi praticamente descontinuado e graphql-http deve ser utilizado ao invés disso. Tomei esta decisão baseada em uma discussão que inclusive recomendava o uso do yoga, uma alternativa mais completa para servidores graphql, no entanto, eu vi que seria completamente capaz de resolver apenas com graphql-htt…  ( 5 min )

    Hashmap status: done
    This week’s post is mainly based on the Hashmap project and is just a brief summary of the project as I did not keep very detailed records, due to many setbacks I had for numerous reasons. I completed the Hashmap project I realised that I hadn’t used node.js to do the Linked List project (and I should have), so for this project, I did not use an index.html and ran my file using node.js from within Visual Studio Code. In order to do this, I had to use VSC debugger and I had to admit that I found it tricky at first. Sometimes nothing happened when I stepped through the code, sometimes nothing got displayed to the console, but I persisted with it and managed to figure out enough to be able to debug and create a working program.

    Troubleshooting Docker: So behebst du Verbindungsfehler beim Arbeiten mit Dockerfiles unter Ubuntu
    Ausgangssituation Eine Docker File zu erstellen, Daraus ein Docker-Image zu bauen, Und von Docker-Image einen Container zu starten. Allerdings habe ich am Anfang ein paar Probleme. Wie ich diese löse, zeige ich Ihnen. Zuerst die "Zugangsdaten" im Docker generieren im Docker erzeugen ❌Das Problem Beim ersten Versuch tritt folgender Fehler auf: Interpretation: Docker versucht, über IPv6 eine Verbindung zu registry-1.docker.io (Docker Hub) herzustellen. Lösungsprozess Netzwerkverbindung prüfen mit ping : ping google.com Verbindung erneut testen Nach der Installation von Netzwerktools wurde die Internetverbindung überprüft. sudo systemctl daemon-reexec Danach wurde der Docker-Vorgang erneut versucht: Ergebnis: Die Verbindung zum Docker Hub war nun erfolgreich, das Problem gelöst. Falls Sie die gleichen Probleme haben, versuchen Sie einfach meine Vorgehensweise. Alternativ können Sie auch die folgenden Aspekte überprüfen: Netzwerktools installieren: sudo apt install iputils-ping curl net-tools IPv6 deaktivieren, wenn häufig Probleme auftreten: sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1 Proxy oder Firewall prüfen, falls das Problem regelmäßig auftritt.

    Threat Modeling Meets Test Planning: A Unified Workflow for Secure Code
    We often treat threat modeling and test planning as two separate disciplines. One belongs to the security team and lives in architecture diagrams. The other belongs to QA and rides shotgun with feature delivery. But in a world where security flaws are more business-critical than ever, this division doesn’t make much sense anymore. What if we stopped treating threat modeling as a theoretical security ritual and started using it as a blueprint for our test plans? What if the same mindset that helps identify potential attack vectors could also guide what we validate, automate, and protect in our test suites? Turns out, it can. Let’s be honest—most development workflows treat security as a checkpoint, not a mindset. You’ll hear “we’ve completed the threat model” during early planning. But week…  ( 5 min )

    🌍 Stop Timezone Chaos in Your Business App: A Laravel Developer’s Guide To Setup User TimeZone Based Carbon Usage
    Timezones are more than just a technical nuisance — they're a real threat to global businesses.

In this post, I’ll show you how I built a timezone conversion tool in Laravel that makes handling multiple timezones easy — even when your users span from Tokyo to Toronto. Let’s dive in. Imagine this: A user in Tokyo schedules a meeting at 2 PM local time. But someone in New York shows up at 1 AM because the app didn’t convert it right. 💀 Or worse: Calendar exports show incorrect times Daylight Saving Time changes break everything twice a year Manual conversions lead to bugs, missed events, and angry customers Sound familiar?

    Why Consistency Matters More Than Motivation (As a Developer)
    Originally published on Medium. Motivation is great — when it shows up. But consistency builds skills, habits, and portfolios. Some days I wake up inspired to build something new. Other days, I don't even want to open my code editor. If I waited for motivation to show up, I'd still be stuck at day one. Motivation is emotional. It depends on sleep, mood, weather, food, dopamine, whatever. It’s not stable. And that’s fine — we’re human. But if we rely on it to work, we’ll work very little. I’ve lost count of how many times I told myself: “I’ll do it tomorrow when I feel more ready.” That tomorrow rarely came. Consistency doesn’t rely on feelings. It’s a system. A rhythm. A muscle. One commit a day One blog post a day One small bug fix Even when it’s not perfect, or exciting, or ideal — it adds up. I stopped overthinking I built projects faster I became more confident I got better — not in a dramatic way, but quietly, steadily Even this blog you’re reading — it exists because I chose to write daily, not when I “felt inspired.” “Write for 15 minutes.” “Fix one component.” Something so small, it feels easy to do — and hard to skip. I don’t care if today’s task is small or ugly. I care that I showed up and made a move. When it comes, I enjoy it. When it’s gone, I work anyway. Motivation is a great bonus. But consistency is what builds portfolios, opens doors, and turns beginners into professionals. Don’t wait for the right moment. Build the rhythm that brings progress — no matter how you feel. Do you rely on motivation, or do you have a system that keeps you moving? Let’s compare notes in the comments. ✍️ Written by @denizgokbudak Frontend developer sharing thoughts on discipline, AI, and real-world dev workflows.  ( 4 min )

    How one bad coder made our stack unbreakable

The code commit comes in and suddenly half of staging is on fire. They push on main, forget semicolons, and somehow manage to brick a Docker container by renaming a folder. At first, we laughed. Then we cried. Then we made rules like “Nobody touches deploy unless it’s Monday–Wednesday, 9 to 5, and you’ve had coffee.” This person, let’s call him Dave, wasn’t just junior. Dave was entropy in human form. If there was a weak spot in the system, Dave would find it not on purpose, just as a side effect of existing. We called him the worst programmer on the team. But we were wrong. Because Dave didn’t just write questionable code he revealed where our system w…  ( 9 min )

If so run: defaults write com.apple.symbolichotkeys.plist AppleSymbolicHotKeys -dict-add 60 "enabled" defaults write com.apple.symbolichotkeys.plist AppleSymbolicHotKeys -dict-add 61 "enabled" This will do the same as unchecking boxes, and will require a reboot to be accounted for, but it probably belongs to your own reinstall script.  ( 3 min )

    CI/CD for Monorepos: Taming the Beast with Smart Strategies 🚀
    Hey there, fellow developer! 👋 Let's talk about something that sounds intimidating but doesn’t have to be: managing CI/CD for monorepos. Imagine your codebase as a bustling city—each project is a neighborhood, and CI/CD is the public transit system keeping everything running smoothly. But when one road closes, you don’t shut down the whole city, right? Let’s explore how to keep your monorepo efficient, scalable, and sane. Why Monorepos? (And Why CI/CD Gets Tricky 🧩) Monorepos are like a shared workspace for your projects: Pros: Unified dependencies, cross-project refactors, and streamlined collaboration. Cons: A single commit can trigger chaos if CI/CD isn’t optimized. The Challenge: Over-testing: Rebuilding everything on every change. Dependency Hell: "Wait, which service u…  ( 4 min )
    Build a One-File EXE with PyInstaller (Including Binaries & Resources)
    Packaging Python projects into standalone executables can be incredibly useful for sharing your work with non-developers. In this guide, we'll walk through how to convert your Python script — even one that depends on additional binaries like ffmpeg or modules like easygui — into a single .exe file using PyInstaller. Let’s have a look at the project structure. Let’s have a quick overview of this project. .venv: The virtual environment that keeps your project isolated and independent. ffmpeg_build: Contains the ffmpeg binaries used in the project. You might not need this specific folder if you’re using other binaries, but the concept of including external binaries remains the same. favicon.ico: The icon file for your application. main.py: The main script containing all the core logic of you…  ( 5 min )

    In-Memory Advisor in Oracle 23ai
    The In-Memory Advisor in Oracle 23ai analyzes database workloads to estimate DB-Time for various In-Memory sizes. Additionally, it can recommend which objects should be placed in the In-Memory column store. To use this feature, you must leverage the DBMS_INMEMORY_ADVISE package. The procedure for running the In-Memory Advisor is similar to the Privilege Analysis feature. To generate advice regarding In-Memory optimization, you first need to start a task and let it analyze the database workload. Once sufficient analysis has been performed, you can stop the task and review the generated report. The following sections detail the steps to generate the report: Step 1: Enable Heat Map SQL> exec dbms_inmemory_advise.start_tracking(:task_id); ORA-20000: Heat map is not enabled.

    🚀 Building and Interacting with a StarkNet Contract using React and StarkNet.js
    🧠 Introduction As blockchain scalability becomes increasingly important, Layer 2 solutions are gaining momentum. Among them, StarkNet stands out due to its use of zero-knowledge proofs (ZK-STARKs) to enable scalable and secure computations. However, StarkNet development involves a unique stack — from Cairo smart contracts to frontend integration via StarkNet.js. In this article, you'll learn how to: Write a Cairo 1.0 smart contract with access control. Deploy it on the StarkNet testnet. Build a frontend using React. Connect it to wallets like Argent X or Braavos. Interact with the contract using StarkNet.js. Let’s start with a simple secure counter contract. Only the contract owner can increment the counter, while anyone can view it. #[starknet::interface] trait ICounterContract<TContra…  ( 5 min )
    Day 1 — The Start of Something Non-Negotiable
    Hi, I’m Mridul Bansal. I’m 18. A first-year student at Newton School of Technology, Pune — but this isn’t about college. This is about a choice I made a few weeks ago: to become one of the top 100 AI/ML minds on the planet in the next 3 years. And I’m documenting everything. Every hour, every line of code, every mental breakdown, every rebuild. This is Day 1 of that journey. But it didn’t start today. In March, I joined offline coaching for Full Stack + AI/ML because YouTube wasn’t enough for me. I’m someone who learns best when I’m all in — environment, people, mindset. So I customized my learning path: Full Stack (MERN) My mindset shifted fast. From just wanting to stay ahead in college → to dominating my batch → to aiming at global level skill. That’s how I landed here. What I Did This Week This past week was about setting foundations — mentally, technically, and emotionally. My Weekly System (Moving Forward) Execution Stack: React.js + MongoDB coming next _ Posting Plan- _ I won’t be posting every day. I’ll post here once a week — just to keep it real and show exactly what I’ve built or learned. No fluff. Just raw execution logs, week by week. Closing Thought- I’m not doing this blog for likes. I’m writing this so that when someone 2 years from now wants to know how I did it — they won’t just see the success, they’ll see the system. No motivation quotes. No branding tricks. Just one guy documenting his rebuild. Let’s build.  ( 4 min )
    Why You Should Finally Move to the Cloud: A Practical Perspective Inspired by Bajaj Finance
    As the Head of Engineering at Bacancy, I often speak with businesses that are hesitant about moving to the cloud. They understand the benefits but worry about the complexity. What if the migration disrupts operations? What if costs go out of control? What if the existing infrastructure is too rigid to support the transition? These are valid concerns. But when a company like Bajaj Finance successfully moves its core lending platform to the cloud, it sends a strong message. If they can do it, so can you. This shift was not just a technical upgrade. It was a clear business decision aimed at making their infrastructure more agile, secure, and ready for growth. Bajaj’s move demonstrates that even the most critical systems can run better in the cloud. And they are not alone. We’ve helped several…  ( 6 min )
    trustthe.dev – A UI Component That Signs Your Work
    “We version packages, sign commits, and write changelogs — but our UIs stay anonymous.” That didn’t sit right with me. So I built trustthe.dev — a minimal UI component that makes your frontend self-describing. The component adds a small, persistent version tag to your UI, revealing: Package version (from package.json) Git commit hash, author, and message Repo + build branch Tech stack humans.txt link Structured schema metadata (ld+json) for the developer It’s SSR-safe, fully customizable, and built with shadcn/ui principles. Install it via the official shadcn CLI: npx shadcn@latest add https://trustthe.dev/r/version.json Then drop the component into your layout. 👀 Why? This isn’t a marketing badge. → Read the trustthe.dev Manifesto If you're a developer who versions, documents, and stands behind their work — this might be for you. 🚀 Next Try it live → trustthe.dev Feedback, forks, and feature requests welcome ✓ Trust the developer.  ( 3 min )

    Do you really know what yield return does?
    The use of yield return in C# has always been a bit of a mystery to me, but recently I’ve come to understand a bit better how it works and when it can be useful. Put simply, yield return allows you to generate values on demand as if they were part of a collection (IEnumerable), without having to manually create or populate a list. Items are returned one by one, only when needed, without storing them all in memory beforehand. Its main advantage lies in supporting lazy evaluation. Imagine you're working on a system that processes data from a large source (maybe a .csv file to be imported or even a .txt log file). In such cases, yield return can optimize memory usage, since it lets you load only one line at a time and begin processing immediately, without waiting to read the entire file. IEnu…  ( 6 min )

    What is UX?
    User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all design aspects and design stages that are around a customer's experience.  ( 3 min )

    Wait... Where Did My Margin Go? 🤯 (Margin Collapsing Explained)
    Do you see anything wrong in below image? 👀 No? 🧐 I have made a minor change do you see what I am talking about now? This is something that tripped me up recently — turns out it’s caused by a little CSS behavior called margin collapsing. 🤔 So, what is Margin Collapsing? As per MDN: The top and bottom margins of blocks are sometimes combined (collapsed) into a single margin whose size is the largest of the individual margins (or just one of them, if they are equal), a behavior known as margin collapsing. Note that the margins of floating and absolutely positioned elements never collapse. In simpler terms: This can make it feel like your margins are “disappearing” — which is exactly what I experienced! 🔧 How to Fix It? .parent { display: flex; /* or grid */ } 🌱 Why This Mattered to Me After some digging, I found this gem of a page: Mastering Margin Collapsing - MDN Highly recommended read if you’ve ever felt CSS was gaslighting you. ✅ TL;DR If vertical margins seem to “disappear”, margin collapsing might be the culprit Happens between block elements’ top/bottom margins Avoid it using display: flex, grid, or some padding Would love to hear if you’ve faced this before — or if this helped you spot a sneaky bug.

    A engenharia não falha a gestão sim: por que times excelentes precisam de gestão excelente
    “Não é a tecnologia que trava o time é a ausência de uma gestão estruturada.” Nos últimos anos, vi de perto o impacto da má gestão técnica: times extremamente talentosos, com stacks modernas e processos de entrega sofisticados, paralisados por falta de clareza, alinhamento e foco. Foi nesse contexto que percebi como a gestão de projetos deixou de ser apenas uma função organizacional e passou a ser um pilar técnico. A engenharia precisa de autonomia, mas também precisa de direção. Não adianta termos um time que domina o React, o Kubernetes ou o GitHub Copilot se os ciclos são confusos, as prioridades mudam a cada reunião e as entregas perdem consistência.

    TWICK - React SDK for Building Video Editors (Captions, Timelines, Effects)
    I have been building a React-based video editing SDK tailored for apps that need to generate, edit, or enhance video content — especially AI-generated content like explainers, reels, and product showcases. As more AI tools pump out video content, one big pain point keeps surfacing: “How do we give users manual control over what the AI just made?” Most AI video tools can generate content — but they fall short when users want to fine-tune it. You get a video, but can’t easily: Add styled captions Adjust scenes Sync audio Edit the timeline Apply effects So I am building a toolkit that lets you embed an editing layer right into your frontend. Here’s a breakdown of what the SDK offers out-of-the-box: Media Utils Extract metadata (video, audio, images) Resize and fit media for different layouts Generate audio visualizers Extract audio from video Media Parser Convert .mov / .webm ➝ .mp4 Compress large video files Handle encoding seamlessly in the background Lambda Integration Export videos via AWS Lambda Save output directly to cloud storage (S3) Timeline Editor Trim, split, and arrange media layers Add & sync text, effects, and audio Timeline-based editing made React-friendly AI-Powered Captions Auto-generate captions from voice/video Apply styled caption themes Live Edit Canvas Drag, resize, rotate video elements Realtime sync with the timeline Live preview as you edit UI Visualizer Panel-based editor Built-in state management (with undo/redo) Effects Engine Canva-style animations: pop, flicker, fade, zoom Text effects: typewriter, staggered, bounce Visual filters for color grading & tone This SDK is ideal for: AI video generation tools (ChatGPT agents, script-to-video platforms) Social media automation apps Product marketing video builders Internal tooling for media teams Watch it in action?

    How I launched and got 1.5k users in 7 days
    Hey everyone, Efficiency Hub, a curated directory of productivity tools built by indie makers. It’s not a huge launch, but it’s a real one. I’ve made $25 so far from my first sponsored app, and what’s more exciting is that people are actually using it, submitting their apps, sharing screenshots, even paying to highlight their tools. I gathered a bunch of feedback from the Reddit community while building it, trying to keep the vibe as authentic and helpful as possible. No bloated AI magic, no VC hype, just a place to showcase solid tools made by focused builders. Some things I did intentionally: Made the submission form super lightweight with optional paid slots Prioritized clarity and trust (you see who made what, and why) Designed it for solo devs and small teams, not big startups If you’re working on something in the productivity space, feel free to submit it. Would love to feature more indie tools that help people get things done without the fluff. Happy to answer questions on setup, pricing, tech, or anything else.  ( 3 min )

    The secret to a long-lasting career in Software Engineering
    In recent times, with Cursor, lovable, and 101 other AI tools, I see many junior developers jumping on the AI bandwagon and just using generators to scaffold code. I also see a great deal of fear in the industry as well, fear that AI will take our jobs. The standards are becoming tougher, it's no longer enough just to know HTML+CSS and a backend language. To survive in modern times, you need to have a deeper understanding of programming and the tools in general. By attending a BootCamp and learning how to build something in [enter framework here], you most certainly can get a job in a few weeks or months' time. However, if you want to survive in the industry for 10+ years and beyond, you need to equip yourself with skills beyond what the market wants today. You should be able to pivot based on demand and grow as the industry changes. To do this, the best place to start is not the docs of [enter framework here]. Rather, it's computer science. Most of the industry has changed a lot in the past 20 years, but actually, the core concepts haven't changed much; thus, learning computer science will help you develop a strong, deeper understanding of how things work and therefore allow you to become a better problem solver. Having been around the block for more than 15 years, I have worked on many, many different problems of varying complexities. Many of these required me to draw on advanced programming and networking knowledge. Anyway, long story short 🙃 I'm working on a series of articles to go deeper into concepts we often ignore as web developers. My goal is to help upskill you into a more complete engineer (and also improve my knowledge too). here's the first article - understanding bits and bytes.  ( 3 min )

    Normal Coding vs. Vibe Coding: Which Style Speaks to Your Dev Soul?
    By Dhanian (@e_opore) Coding is more than just typing lines into an editor—it’s a craft, a puzzle, and for many of us, a deeply personal journey. Over time, I’ve danced between two wildly different approaches: normal coding—disciplined, logical, structured—and vibe coding—fluid, music-fueled, and sometimes beautifully chaotic. Both have shaped me as a developer. One grounds me, the other frees me. Today, I’m sharing their magic, quirks, and how you can find your rhythm between the two. Plus, I’ll introduce a resource I built to help you level up your style—available now on Gumroad.

    The Subtle Corrosion of Code: How Gresham's Law Applies to Software Development
    In economics, Gresham's Law teaches us that "bad money drives out good." A powerful analogy, and surprisingly pertinent, permeates the daily life of software engineering: low-quality code tends to supplant well-crafted code. In a software development ecosystem often pressured by tight deadlines and continuous deliveries, the temptation to opt for quick and superficial solutions ("bad code") can become overwhelming. Although these approaches may offer short-term gains, they insidiously undermine the health and sustainability of our projects. The Mechanisms of Degradation: The "driving out" of good code by bad code is not a sudden event, but a gradual process driven by several factors: The Shortcut of Immediate Implementation: Under pressure, creating low-quality code, focused on the immed…  ( 5 min )

    Read the full story here → What 117 Days of Reflection Taught Me About Crafting Code That Endures For 117 days, I've been writing a short reflection every morning. At first, it was just a quiet ritual. A way to center myself before diving into code. But over time, it became something else. I started noticing patterns in how I approached problems, how I rushed when I should have paused, and how often I worked around I should have worked through it. These reflections reminded me of the kind of developer I want to be. One who builds with care and writes code that stays strong when things get messy. Here are a few lessons that stuck: Each day, I pair a short insight with a quote from the Stoics. Not to sound wise, but to stay grounded.

    🚀 Kotlin's Key Features #1
    🏹 Null Safety in Kotlin Dodging the Null Pointer Exception, the Kotlin way🤓🤓 ➤ Concept of Strict Null Safety in Kotlin • Safe Call Operator ( ?. ) in Kotlin ( ?: ) in Kotlin ( !! ) in Kotlin. Kotlin allows to store “Null” values in a variable. In Kotlin, the variables can be made of Null types by just adding a “?” symbol to the right side of the data type. A nullable type variable means it can also hold “Null” as a value in it. A non-nullable type variable means that it can not hold “Null” as a value in it. The safe call operator is simply a question mark followed by a dot ( ?. ) The safe call operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the left-hand side of the operator is null, then it will return null value. If the left-hand side of the operator is not null, then it will return the result of the right-hand side expression. The elvis operator is represented by a question mark followed by a colon ( ?: ) The elvis operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the first operand is not null, then this operand will be returned by the elvis operator. If the first operand is null, then second operand will be returned by the elvis operator. The Not Null Assertion is represented by a double exclamation mark (!!) The Not Null Assertion in Kotlin, is another tool to deal with nullity. This operator explicitly casts nullable variables to non-nullable variables.  ( 3 min )

    The original motivation for creating Lean was software verification
    "The main motivation, the original motivation for (creating) Lean was in software verification, right? I mean, Z3 was very popular at bug finding, for bug finding at Microsoft, was very influential there. But (for) Lean the goal was, can we make the same, have the same success of software verification? We went to a very strange path. I mean, having impact in mathematics that we never dreamt of. But the goal in both cases is like we, both in software mathematics and in AI, today rely on manual review, partial testing. A mistake in a theorem can be catastrophic, invalidating the whole result. The same thing (happens) for a critical piece of software, right? And one thing I see all the time, people fearing to make a change a piece of software because they fear by making the change they may be introducing a bug, especially if it's a critical piece of software."

The Challenge 100 days, 100 commits: Atomic backend projects pushed to https://github.com/joshylak/100-backend-projects Tech Stack: Sample Battle Plan Phase 1: Core Systems (Days 1-30) Day 1: Bare-metal HTTP server (no Express) Day 12: Connection pool leak detector Day 23: JWT blacklist with Redis Lua scripts Phase 2: Pain Points (Days 31-70) Day 37: N+1 query exterminator Day 45: Distributed deadlock simulator Day 63: Postgres failover with pg-rewind Phase 3: Bloody Edge Cases (Days 71-100) Day 82: WebSocket flood attack mitigator Day 91: CTE-based RBAC permission tree Day 100: Zero-downtime schema migrations Why This Matters No ORMs allowed: Raw SQL or bust. Instrumentation-first: Every service gets Prometheus metrics. Failure-driven: I'll intentionally build: 🔗 https://github.com/joshylak/100-backend-projects For Developers Call me out if you see await in loops or JSON.parse() without try/catch Suggest a nightmare scenario (e.g., "Implement Serializable isolation with retries") Steal the vicious parts: Transaction retry logic, prepared statement caches )  ( 3 min )
    15 dev survival lessons from someone who actually made it
    Real-world insights from the trenches of senior engineering no fluff, no gatekeeping, just hard-earned truths Introduction Let’s be honest: the internet is overflowing with feel-good developer advice. “Write clean code.” “Use version control.” Cool story, bro. But what happens when you’re neck-deep in a spaghetti codebase with legacy bugs older than your GitHub account? That’s where real lessons begin. I was lucky and unlucky enough to work under a principal engineer who didn’t sugarcoat anything. Think senior dev meets Jedi master, minus the lightsaber and plus a ton of passive-aggressive code reviews. He didn’t just teach me how to write better code he rewired how I think as a developer. This isn’t another list of beginner tips. These are 15 survival rules forged in production fires, arc…  ( 13 min )
    Redis 8 just dropped: back to open source and ready to reclaim its crown
    After backlash, a fork, and a community exodus, Redis is rolling out v8 open source again, and stacked with features. But is it too little, too late? Introduction A few months back, we talked about the quiet revolution happening in the in-memory data world how Valkey, the community-led fork of Redis, was suddenly gaining traction after Redis Inc. decided to lock the doors on full open source. If you missed that breakdown, catch up here: Why Redis is losing friends and Valkey is gaining them But now, in a dramatic plot twist worthy of a season finale, Redis 8 is here, and it’s back with something most devs didn’t expect: a full return to open source under the BSD license. Not just that Redis 8 ships with real upgrades, not just a PR apology. Faster I/O threads, memory optimizations, smarter…  ( 8 min )

    Junior vs Mid vs Senior Developer: What’s the Real Difference?
    “Same title. Same job. Very different outcomes.” If you've ever worked on a dev team, you’ve probably noticed it: not all developers with the same title operate at the same level. Some juniors write better code than mids. Some seniors… well, are just loud middles. So what actually separates a junior developer from a mid-level or senior engineer? Is it years of experience? Code quality? Confidence in meetings?

    Why Linking your Test Scripts with the Test Management Tool is a Game-Changer!
    Let’s talk about something that often gets overlooked in the hustle of automation, syncing your automated test scripts with your test management system! You might think, “Eh, my tests run fine. I’ve got my green ticks on the pipeline. Why bother?” Well, hold onto that thought, because today I’m going to show you why this link is not just a nice-to-have but a superpower for your test automation efforts! What do I mean by Linking? At its core, linking means there’s a direct connection between the test cases you’ve written in your test management tool (like TestRail, Azure Test Plans, XRay, etc.) and the actual automation scripts you’ve coded up in your framework (Cypress, Playwright, Selenium — you name it). This sync can be manual (you link test IDs in your scripts) or fully automated. Wh…  ( 6 min )

    Rediscovering ACID – The Foundation of Reliable Databases
    As engineers, we use transactions all the time — BEGIN, COMMIT, and maybe a rollback if things go south. But recently, I realized I hadn’t truly internalized what makes those transactions reliable. That curiosity led me to revisit the ACID properties — a foundational concept we all learn early on but rarely pause to deeply understand. What started as a quick refresher turned into a deep dive into atomicity, consistency, isolation, and durability, and how real databases like PostgreSQL and MySQL implement them. Along the way, I discovered that one core mechanism — the Write-Ahead Log (WAL) — is key to both Atomicity and Durability, playing a foundational role in keeping transactions safe and recoverable. In this first part of a multi-part series, I’ll walk through what each property means, …  ( 5 min )
    Python for Oracle on ARM Linux | Part 2 - "shell like" SQL scripts
    { Abhilash Kumar Bhattaram : Follow on LinkedIn } NOTE : The blog examples is on ARM Linux but almost the same works for x86 if as long as you have the required miniconda environment. In traditional DBA workflows, shell scripts are commonly used to automate database tasks such as executing SQL files, capturing logs, and scheduling jobs. However, this blog demonstrates how Python can serve as a modern and powerful alternative to shell scripting for Oracle DBAs. By leveraging Python’s subprocess module, we show how to run SQL*Plus commands, manage SQL script execution, redirect output to spool files, and even handle background processes—all within a clean and maintainable Python environment. This approach not only improves readability and cross-platform compatibility but also enables integr…  ( 8 min )

    Avoid Memory Leaks in Angular When Using takeUntil with Higher-Order RxJS Operators
    When working with Angular and RxJS, takeUntil is a common operator for unsubscribing from observables, especially in component lifecycle management. However, if you're using takeUntil incorrectly with higher-order mapping operators like mergeMap, switchMap, concatMap, exhaustMap, you may still end up with memory leaks. A common mistake is placing takeUntil before a higher-order operator in your observable pipeline. This seems logical, but it doesn't always behave as expected. When takeUntil is upstream of a higher-order operator, it won't effectively unsubscribe the inner subscription created by that operator. this.counterB$.pipe( takeUntil(this.destroySubject), mergeMap((value) => this.counterA$) ).subscribe(...); In the example above, the outer observable (counterB$) is unsubscribed…  ( 4 min )

    What is GO
    GO or GOlang Introduction Go(or GoLang) is a popular low-level programming language developed by Google in 2007. And that's what we are going to cover in this blog. What is GO? How was it developed? Why should you consider learning GO? So let's not waste our time and jump in. GO is a general-purpose programming language. It is statically typed and compiled. It is known for its simplicity of syntax and a better developer experience than other programming languages in the same niche, like: C C++ Rust A statically typed language is one where the type checking is completed at compile time, meaning the data type of each variable (string, integer, etc.) is known before the program runs and cannot be changed afterwards. Many people get confused and think that GO is both statically and dynamically typed because: x := 2 //Dynamically declared (GO's Type interface decides the type). var y int = 4 //Statically declared. Both ways can be used to declare variables in GO. But then why do we say it's statically typed? Because in a statically typed language like GO, you cannot do: x := 2 and then x = "two". Doing this will cause a compilation error. But in dynamically typed languages like JavaScript, you can do the same thing as x = 2 x = 'two' console.log(x) And it will work fine. GO was developed by Google in 2007. The designers wanted to address the issues they felt with the language they used at that time, but keep their useful characteristics. Go was publicly announced in November 2009, and the first version was released in 2012. Now, this language is actively used in the world. It’s Simple and easy, unlike Rust, C++, and C. First Class Concurrency Performance Proven Track Record + Job Demand And that's why you should prefer learning GO.

    How does quoting works in ArkScript macros?
    The other night, I was talking about meta programming to other developers, and at one point someone asked how macros could be used to do meta programming. They were probably thinking about C type of macros, which are powerful but are just text processor tools. Using macros you could have the following code: double Compute() { // doing something return result; } and transform it into: double Compute() { if (_cache.GetValue(out var result) return result; // doing something _cache.SetValue(result); return result; } They are a tool to manipulate code, with code. It allows one to write generic code and have the compiler do the heavy lifting and monomorphize your code. What's meta programming?

    Why I’m Building a Dopamine Tracker
    In early 2025, I realized something uncomfortable: I was spending hours every day switching between tabs, endlessly scrolling, and jumping between distractions — and I didn’t even realize how often it was happening. Like many developers and students, I use a computer all day. But I noticed a pattern of compulsive behavior that wasn’t productive. I wasn’t just “working online.” I was switching contexts 50+ times an hour — email, YouTube, Reddit, docs, social media, GitHub… repeat. I wanted to understand my dopamine loops — those invisible triggers and habits that push me to seek micro-hits of pleasure instead of focusing on deep work. That’s why I started building Dopamine Tracker — a minimal, privacy-focused tool that: tracks online behavior via a browser extension, stores it in a Supabase backend, and visualizes patterns through a React dashboard. It’s not about guilt or blocking websites — it’s about insight and agency. Right now, the extension logs: Active tab time App switches and focus changes Time-of-day usage Top “dopamine drivers” (based on frequency + context) Everything is stored locally in local storage as for the alpha stage. I’m sharing this journey to: document the technical process (React, Supabase, browser APIs), reflect on design choices and architecture, connect with others working on similar problems. If you’ve ever found yourself working but not really working — this project might speak to you. In the coming weeks, I’ll share devlogs on: implementing dopamine tracking and scoring algorithms designing the extension UI, building the analytics dashboard, Thanks for following along. Let’s see where this goes. Stay mindful, stay focused. — Pietrell  ( 3 min )

Integrating AI assistants with these sources required bespoke connectors, resulting in the infamous N×M integration problem: every new model needed custom cod…  ( 6 min )
    Deep Copy vs Shallow Copy in JavaScript: Complete Guide
    Understanding Object References in JavaScript Have you ever changed something you thought was a separate copy, only to find you messed up the original data too? Yeah, that happens a lot if you don't get how JavaScript handles different kinds of copying; deep copy vs shallow copy. JavaScript has these two main ways it thinks about data: by value and by reference. Simple stuff like numbers, strings, booleans, null, and undefined are value types. When you copy them, JavaScript just makes a whole new one. A separate thing entirely. Changing the new one never affects the old one. let a = 10; let b = a; // b gets a copy of the value 10 b = 20; console.log(a); // Output: 10 (a is unchanged) However, objects, arrays, and functions are reference types. When you assign one variable to another, yo…  ( 10 min )

    😄 Built a fun little project to calculate how ancient you are... and sneakily learned Docker in the process!
    This is a basic Go lang project that shows your age if you know your birth year. In this, you have to input your birth year, and it will take the current year automatically. By using the formula Current Year - Birth Year, it shows your current age. This project is mainly intended to learn how to containerize an application. It is not a Go-focused project but mainly Docker-focused instead. A Dockerfile will be created to build a Docker image and run it inside a container. Once containerized, the application can be run easily using Docker commands on any system that supports Docker, regardless of the host environment. This helps demonstrate the power of containerization and the portability it brings to software development. The project will also serve as a base to practice Docker fundamentals like: -> Writing a Dockerfile -> Building a lightweight image for a Go application -> Running the image as a container -> Understanding how to manage input/output inside the container Overall, this project provides a practical, beginner-friendly example of containerizing a simple application — making it a great starting point for learning Docker and DevOps workflows.

    Don’t believe the noise: There can never be too many L2s
